CYV15G0404RB receive data path serial line receivers two differential line receivers, inx1 and inx2, are available on each channel to accept serial data streams. the associated inselx input selects the active serial line receiver on a channel. the serial line receiver inputs are differential, and can accommodate wire interconnect and filtering losses or transmissi on line attenuation greater than 16 db. for normal operation, these inputs must receive a signal of at least vi diff > 100 mv, or 200 mv peak-to-peak differential. each line receiver can be dc or ac coupled to +3.3v powered fiber-optic interface modules (any ecl/pecl family, not limited to 100k pecl) or ac coupled to +5v powered optical modules. the common mode tolerance of these line receivers accommodates a wide range of signal termination voltages. each receiver provides internal dc restoration, to the center of the receiver?s common mode range, for ac coupled signals. signal detect/link fault each selected line receiver (that is, that routed to the clock and data recovery pll) is simultaneously monitored for ? analog amplitude above amplitude level selected by sdaselx ? transition density abov e the specified limit ? range controls reporting the received data stream inside normal frequency range (1500 ppm [21] ) ? receive channel enabled ? reference clock present ?ulcx not asserted. all of these conditions must be valid for the signal detect block to indicate a valid signal is present. this status is presented on the lfix (link fault indicator) output associated with each receive channel, which changes synchronous to the receive interface clock. analog amplitude while most signal monitors are based on fixed constants, the analog amplitude level detection is adjustable to allow operation with highly attenuated signals, or in high noise environments. the sdaselx latc h sets the an alog amplitude level detection via the device configuration interface. the sdaselx latch sets the trip point for the detection of a valid signal at one of three levels, as listed in ta b l e 1 . this control input affects the analog monitors for all receive channels. the analog signal detect monitors are active for the line receiver, as selected by the associated inselx input. transition density the transition detection logi c checks for the absence of transitions spanning greater than six transmission characters (60 bits). if there are no trans itions in the data received, the detection logic for that channel asserts lfix . range controls the cdr circuit includes logic to monitor the frequency of the pll voltage controlled oscillator (vco) samples the incoming data stream. this logic ensures that the vco tdo 3-state lvttl output test data out . jtag data output buffer. high-z while jtag test mode is not selected. tdi lvttl input, internal pull up test data in . jtag data input port. trst lvttl input, internal pull up jtag reset signal . when asserted (low), this input asynchronously resets the jtag test access port controller. power v cc +3.3v power . gnd signal and power ground for all internal circuits . pin definitions (continued) CYV15G0404RB quad hotlink ii deserializing reclocker name io characteristics signal description table 1. analog amplitude detect valid signal levels [5] sdasel typical signal with peak amplitudes above 00 analog signal detector is disabled 01 140 mv p-p differential 10 280 mv p-p differential 11 420 mv p-p differential note 5. the peak amplitudes listed in this table are for typical wavefo rms that generally have 3?4 tr ansitions for every ten bits. in a worst case environment the signals may have a sine-wave appearance (highest tran sition density with repeating 0101...). signal peak amplitudes levels within this environment type could increase the values in the table above by approximately 100 mv.

? when the incoming data stream is outside the acceptable signaling rate range. to perform this function, periodically compare the frequency of the rxpll vco to the frequency of the trgclkx input. if the vco is running at a frequency beyond 1500 ppm [21] as defined by the trgclkx frequency, it is periodically forced to the correct frequency (as defined by trgclkx, spdselx, and trgratex) and then released in an attempt to lock to the input data stream. calculate the sampling and relock period of the range control as follows: range_cont rol_sampling_period = (recovered byte clock period) * (4096). during the time that the range control forces the rxpll vco to track trgclkx, the lfix output is asserted low. after a valid serial data stream is applied, it may take up to one range control sampling period before the pll locks to the input data stream, after which lfix is high. ta b l e 2 lists the operating serial signaling rate and allowable range of trgclk frequencies. receive channel enabled the CYV15G0404RB contains four receive channels that it can independently enable and disable. each channel are enabled or disabled separately through the rxpllpdx input latch as controlled by the device configuration interface. rxpllpdx latch = 0 disables the associated pll and analog circuitry of the channel. any disabled channel indicates a constant link fault condition on the lfix output. rxpllpdx = 1 enables the associated pll and receive channel to receive a serial stream. note when a disabled receive channel is reenabled, the status of the associated lfix output and data on the parallel outputs for the associated channel may be indeterminate for up to 2 ms. clock/data recovery a separate cdr block within each receive channel performs the extraction of a bit rate clock and recovery of bits from each received serial stream. an in tegrated pll that tracks the frequency of the transitions in the incoming bit stream and aligns the phase of the internal bit rate clock to the transitions in the selected serial data stream performs the clock extraction function. each cdr accepts a character-rate (bit-rate 10) or half-character-rate (bit-rate 20) training clock from the associated trgclkx input. this trgclkx input is used to ? ensure that the vco (within the cdr) is operating at the correct frequency (rather than a harmonic of the bit rate) ? reduce pll acquisition time ? limit unlocked frequency excursions of the cdr vco when there is no input data present at the selected serial line receiver. regardless of the type of signa l present, the cdr attempts to recover a data stream from it. if the signaling rate of the recovered data stream is outside the limits set by the range control monitors, t he cdr tracks trgclkx instead of the data stream. once the cdr output (rxclk) frequency returns close to trgclkx frequency, the cdr input switches back to the input data stream. if no data is present at the selected line receiver, this switching behavior may cause brief rxclk frequency excursions from trgclkx. however, the lfix output indicates the validity of the input data stream. the frequency of trgclkx must be within 1500 ppm [21] of the frequency of the cloc k that drives the reference clock input of the remote transmitter, to ensure a lock to the incoming data stream. this large ppm tolerance allows the cdr pll to reliably receive a 1.485 or 1.485/1.001 gbps smpte hd-sdi data stream with a constant trgclk frequency. for systems using multiple or redundant connections, use the lfix output to select an alternate data stream. when the device detects an lfix indication, external logic toggles selection of the associated inx1 and inx2 input through the associated inselx input. when a port switch takes place, the receive pll for that channel reacquires the new serial stream. reclocker each receive channel performs a reclocker function on the incoming serial data. to do this, the clock and data recovery pll first recovers the clock from the data. the recovered clock retimes the data and then passes it to an output register. it also passes the recovered character clock from the receive pll to the reclocker output pll, which generates the bit clock that clocks the retimed data into t he output register. this data stream is then transmitted th rough the differential serial outputs. reclocker serial output drivers the serial output interface dr ivers use differential current mode logic (cml) drivers to provide source-matched drivers for 50 ? transmission lines. these drivers accept data from the reclocker output register in the reclocker channel. these drivers have signal swings equivalent to that of standard pecl drivers, and can drive ac coupled optical modules or trans- mission lines. reclocker output channels enabled each driver can be enabled or disabled separately via the device configuration interface. when a driver is disabled using the configuration interface, it internally powers down to reduce device power. if both table 2. operating speed settings spdselx trgratex trgclkx frequency (mhz) signaling rate (mbps) low 1 reserved 195?400 0 19.5?40 mid (open) 1 20?40 400?800 0 40?80 high 1 40?75 800?1500 0 80?150 [+] feedback [+] feedback
CYV15G0404RB document #: 38-02102 rev. *c page 13 of 27 reclocker serial drivers for a channel are in this disabled state, the associated internal reclocker logic also powers down. the deserialization logic and parallel outputs remain enabled. a device reset (reset sampled low) disables all output drivers. note when the disabled reclocker function (that is, both outputs disabled) is reenabled, the data on the reclocker serial outputs may not meet all timing specifications for up to 250 s. output bus each receive channel presents a 10-bit data signal (and a bist status signal when rxbistx[1:0] = 10). receive bist operation each receiver channel contains an internal pattern checker that is used to validate both device and link operation. these pattern checkers are enabled by the associated rxbistx[1:0] latch through the device conf iguration interface. when enabled, a register in the associated receive channel becomes a signature pattern generator and checker by logically converting to a linear feedback shift register (lfsr). this lfsr generates a 511-characte r sequence. this provides a predictable, yet pseudorandom, sequence that can be matched to an identical lfsr in the attached transmitter(s). when synchronized with the received data stream, the associated receiver checks eac h character from the deseri- alizer with each character generated by the lfsr and indicates compare errors and bist status at the rxdx[1:0] and biststx bits of the output register. the bist status bus {biststx, rxdx[0], rxdx[1]} indicates 010b or 100b for one character period per bist loop to indicate loop completion. use this status to check test pattern progress. table 5, ?receive bist status bits,? on page 17 lists the specific status reported by the bist state machine. the receive status outputs report these same codes. if the number of invalid characters received exceeds the number of valid characters by 16, the receive bist state machine aborts the compare operations and resets the lfsr to look for the start of the bist sequence again. a device reset (reset sampled low) presets the bist enable latches to disable bist on all channels. bist status state machine when a receive path is enabled to look for and compare the received data stream with the bist pattern, the {biststx, rxdx[0], rxdx[1]} bits identify the present state of the bist compare operation. the bist state machine has multiple states, as shown in figure 2, "receive bist state machine," on page 18 and table 5, ?receive bist status bits,? on page 17 . when the receive pll detects an out-of-lock condition, it forces the bist state to the start-of-bist state, regardless of the present state of the bist state machine. if the number of detected errors ever exceeds the number of valid matches by greater than 16, the state machine is forced to the wait_for_bist state, where it monitors the receive path for the first character of the next bist sequence. power control the CYV15G0404RB supports user control of the powered up or down state of each transmit and receive channel. the rxpllpdx latch controls the receive channels through the device configuration interface. rxpllpdx = 0 disables the associated pll and analog circuitry of the channel. the oe1x and the oe2x latches control the transmit channels via the device configuration interfac e. the roe1x and the roe2x latches control the reclocker function through the device configuration interface. when the configuration interface disables a driver, the driver in ternally powers down to reduce device power. if both serial drivers for a channel are in this disabled state, the associated internal logic for that channel also powers down. the reclocker serial drivers being disabled in turn disables the reclocker function, but the deserialization logic and parallel outputs remain enabled. device reset state assertion of reset resets all state machines, counters, and configuration latches in the device to a reset state. additionally, the jtag controller must be reset for valid operation (even if not performing jtag testing). see ?jtag support? on page 17 for jtag state machine initialization. see table 3, ?device configuration and control latch descrip- tions,? on page 14 for the initialize values of the configuration latches. following a device reset, enable the receive channels used for normal operation. do this by sequencing the appropriate values on the device configuration interface. [3] device configuration and control interface configure the CYV15G0404RB through the configuration interface. the configuration interface enables the device to be configured globally or enables each channel to be configured independently. table 3, ?device configuration and control latch descriptions,? on page 14 lists the configuration latches within the device, including the initialization value of the latches on the assertion of reset . table 4, ?device control latch configuration table,? on page 16 shows how the latches are mapped in the device. each row in ta b l e 4 maps to an 8-bit latch bank. there are 16 such write only latch banks. when wren = 0, the logic value in the data[7:0] latches to the latch bank specified by the values in addr[3:0]. the second column of table 4 specifies the channels associated with the corresponding latch bank. for example, the first three latch banks (0, 1, and 2) consist of configuration bits for channel a. latch banks 12, 13, and 14 consist of global configuration bits, and the last latch bank (15) is the mask latch bank, which can be configured to perform bit-by-bit configuration. global enable function the global enable function, cont rolled by the glenx bits, is a feature that can reduce the number of write operations needed to set up the latch banks. this function is benef icial in systems that use a common configuration in multiple channels. the glenx bit is present in bit 0 of latch banks 0 through 11 only. its default value (1) enables the global update of the latch bank's contents. setting the glenx bit to 0 disables this functionality.

and wren is asserted. the signals present in data[7:0] effectively become global control pins, and for the latch banks 2, 5, 8, and 11. static latch values there are some latches in the table that have a static value (that is, 1, 0, or x). the latches that have a ?1? or ?0? must be configured with their corresponding value each time that their associated latch bank is confi gured. the latches that have an ?x? are don?t cares and can be configured with any value table 3. device configuration and control latch descriptions name signal description rxratea rxrateb rxratec rxrated receive clock rate select . the initialization value of the rxratex latch = 1. rxratex selects the rate of the rxclkx clock output. when rxratex = 1, the rxclkx clock outputs ar e complementary clocks th at follow the recovered clock operating at half the character rate. data for th e associated receive channels must latch alternately on the rising edge of rxclkx+ and rxclkx?. when rxratex = 0, the rxclkx clock outputs ar e complementary clocks th at follow the recovered clock operating at the character rate. data for the associated receive channels must latch on the rising edge of rxclkx+ or falling edge of rxclkx?. sdasel1a[1:0] sdasel1b[1:0] sdasel1c[1:0] sdasel1d[1:0] primary serial data input sign al detector amplitude select . the initialization value of the sdasel1x[1:0] latch = 10. sdasel1x[1:0] selects the trip point for the detection of a valid signal for the inx1 primary differential serial data inputs. when sdasel1x[1:0] = 00, the analog signal detector is disabled. when sdasel1x[1:0] = 01, the typical p-p differential voltage threshold level is 140 mv. when sdasel1x[1:0] = 10, the typical p-p differential voltage threshold level is 280 mv. when sdasel1x[1:0] = 11, the typical p-p differential voltage threshold level is 420 mv. sdasel2a[1:0] sdasel2b[1:0] sdasel2c[1:0] sdasel2d[1:0] secondary serial data input signal detector amplitude select . the initialization value of the sdasel2x[1:0] latch = 10. sdasel2x[1:0] selects the trip point for the detection of a valid signal for the inx2 secondary differential serial data inputs. when sdasel2x[1:0] = 00, the analog signal detector is disabled when sdasel2x[1:0] = 01, the typical p-p differential voltage threshold level is 140 mv. when sdasel2x[1:0] = 10, the typical p-p differential voltage threshold level is 280 mv. when sdasel2x[1:0] = 11, the typical p-p differential voltage threshold level is 420 mv. trgratea trgrateb trgratec trgrated training clock rate select . the initialization value of the trgratex latch = 0. trgratex selects the clock multiplier for the training clock input to the associated cdr pll. when trgratex = 0, the associated trgclkx input is not multiplied before it is passed to the cdr pll. when trgratex = 1, the trgclkx input is multiplied by 2 before it is passed to the cdr pll. trgratex = 1 and spdselx = low is an invalid state and this combination is reserved.
