General Description
The VSC7182 is a full-speed quad Fibre Channel and Gigabit Ethernet transceiver IC. Each of the four transmitters has a 10-bit wide bus, running up to 136MHz, which accepts 8B/10B encoded transmit characters and serializes the data onto high-speed differential outputs at speeds up to 1.36Gb/s. The transmit data can be synchronous to the reference clock, a common transmit byte clock or a per-channel transmit byte clock. Each receiver samples serial receive data, recovers the clock and data, deserializes it into 10-bit receive characters, outputs a recovered clock and detects "Comma" characters. The VSC7182 contains on-chip Phase-Lock Loop (PLL) circuitry for synthesis of the baud-rate transmit clock and extraction of the clocks from the received serial streams. The VSC7182 also includes a receiver squelch circuit to control the parallel data bus in the absence of serial input.

Functional Description
Notation In this document, each of the four channels are identified as Channel A, B, C or D. When discussing a signal on any specific channel, the signal will have the Channel letter embedded in the name, for example, "TA[0:9]". When referring to the common behavior of a signal which is used on each of the four channels, a lower case "x" is used in the signal name, i.e. TXi[0:9]. Differential signals, such as RA+ and RA-, may be referred to as a single signal, i.e. RA, by dropping reference to the "+" and "-". "RFC" refers to either the TTL input RFCT, or the PECL differential inputs RFC+/RFC-, whichever is used. Clock Synthesizer The VSC7182 clock synthesizer multiplies the reference frequency provided on the RFC input by 10 or 20 to achieve a baud rate clock between 1.05GHz and 1.36GHz. The RFC input can be either TTL or PECL. If TTL, connect the TTL input clock to RFCT. If PECL, connect the PECL inputs to RFC+ and RFC-. The internal clock presented to the clock synthesizer is a logical XNOR of RFCT and RFC+/-. The reference clock will be active HIGH if the unused input is HIGH. The reference clock is active LOW if the unused input is LOW. RFCT has an internal pull-up resistor. Internal biasing resistors set the proper DC level on RFC+/- so AC-coupling may be used. The TTL outputs, RFCO0 and RFCO1, provide a clock that is frequency-locked to the RFC input. This clock is derived from the clock synthesizer and is always 1/10th the baud rate, regardless of the state of the RFCM input. The on-chip PLL uses a single external 0.1F capacitor, connected between CAP0 and CAP1, to control the loop filter. This capacitor should be a multilayer ceramic dielectric, or better, with at least a 5V working voltage rating and a good temperature coefficient (NPO is preferred but X7R may be acceptable). These capacitors are used to minimize the impact of common-mode noise on the Clock Multiplier Unit (CMU), especially power supply noise. Higher value capacitors provide better robustness in systems. NPO is preferred because if an X7R capacitor is used, the power supply noise sensitivity will vary with temperature. For best noise immunity, the designer may use a three capacitor circuit with one differential capacitor between CAP0 and CAP1, C1, a capacitor from CAP0 to ground, C2, and a capacitor from CAP1 to ground, C3. Larger values are better but 0.1F is adequate. However, if the designer cannot use a three capacitor circuit, a single differential capacitor, C1, is adequate. These components should be isolated from noisy traces. Figure 1: Loop Filter Capacitors (Best Circuit)

Serializer The VSC7182 accepts TTL input data as a parallel 10-bit character on the TXi[0:9] bus which is latched into the input register on the rising edge of either RFC or TCi. Three clocking modes are available and automatically detected by the VSC7182. If TCC is static and RFCM is HIGH, then all four TXi[0:9] busses are latched on the rising edges of RFC. If TCC is static and RFCM is LOW, then RFC is multiplied by 20 and the input busses are latched on the rising edges of RFC and at the midpoint between rising edges. If TCC is toggling but TCB is static, then all four TXi[0:9] busses are latched on the rising edges of TCC. If TCB and TCC are both toggling then the rising edge of each TCi latches the corresponding TXi[0:9] bus. The active TCC or TCi inputs must be frequency-locked to RFC. There is no specified phase relationship. Prior to normal data transmission, LTCN must be asserted LOW so the VSC7182 can lock to TCi, which may result in corrupted data being transmitted. Once LTCN has been raised HIGH, the transmitters remain locked to RFC and can tolerate +/-2 bit times of drift in TCi relative to RFC. The 10-bit parallel transmission character will be serialized and transmitted on the TXi PECL differential outputs at the baud rate with bit TXi0 (bit A) transmitted first. User data should be encoded using 8B/10B or an equivalent code. The mapping to 10B encoded bit nomenclature and transmission order is illustrated below, along with the recognized comma pattern.

Clock Recovery The VSC7182 accepts differential high-speed serial input from the selected source (either the PECL SI+/ SI- pins or the internal TXi+/- data), extracts the clock and retimes the data. Equalizers are included in the receiver to open the data eye and compensate for InterSymbol Interference (ISI) which may be present in the incoming data. The serial bit stream should be encoded so as to provide DC balance and limited run length by an 8B/10B encoding scheme. The digital Clock Recovery Unit (CRU) is completely monolithic and requires no external components. For proper operation, the baud rate of the data stream to be recovered should be within +200 ppm of ten times the RFC frequency. For example, Gigabit Ethernet systems would use 125MHz oscillators with a +100ppm accuracy resulting in +200 ppm between VSC7182 pairs. Deserializer The recovered serial bit stream is converted into a 10-bit parallel output character. The VSC7182 provides complementary TTL recovered clocks, RCi0 and RCi1, which are at 1/20 th of the serial baud rate (if RCM=LOW) or 1/10th (if RCM=HIGH). The clocks are generated by dividing down the high-speed recovered clock which is phase-locked to the serial data. The serial data is retimed, deserialized and output on RXi[0:9]. If serial input data is not present, or does not meet the required baud rate, the VSC7182 will continue to produce a recovered clock so that downstream logic may continue to function. The RCi0/RCi1 output frequency under these circumstances will differ from its expected frequency by no more than +1%. A receiver squelch circuit forces the parallel data output bus to all ones if the serial receiver input level is less than 100mV differential peak-to-peak.

Word Alignment The VSC7182 provides 7-bit comma character recognition and data word alignment. Word synchronization is enabled on all channels by asserting SYNC HIGH. When synchronization is enabled, the receiver examines the recovered serial data for the presence of the "Comma" pattern. This pattern is "0011111XXX", where the leading zero corresponds to the first bit received. The comma sequence is not contained in any normal 8B/10B coded data character or pair of adjacent characters. It occurs only within special characters, known as K28.1, K28.5 and K28.7, which are defined for synchronization purposes. Improper comma alignment is defined as any of the following conditions: 1) The comma is not aligned within the 10-bit transmission character such that RXi(0...6) = "0011111." 2) The comma straddles the boundary between two 10-bit transmission characters. 3) The comma is properly aligned but occurs in the received character presented during the rising edge of RCi0 rather than RCi1. When SYNC is HIGH and an improperly aligned comma is encountered, the recovered clock is stretched, never slivered, so that the comma character and recovered clocks are aligned properly to RXi[0:9]. This results in proper character and word alignment. When the parallel data alignment changes in response to a improperly aligned comma pattern, data which would have been presented on the parallel output port prior to the comma character, and possibly the comma character itself, may be lost. Possible loss of the comma character is data dependent, according to the relative change in alignment. Data subsequent to the comma character will always be output correctly and properly aligned. When SYNC is LOW, the current alignment of the serial data is maintained indefinitely, regardless of data pattern. On encountering a comma character, SYNi is driven HIGH. The SYNi pulse is presented simultaneously with the comma character and has a duration equal to the data. The SYNi signal is timed such that it can be captured by the adjoining protocol logic on the rising edge of RCi1. Functional waveforms for synchronization are given in Figure 2. The first K28.5 shows the case where the comma is detected, but it is misaligned so a change in the output data alignment is required. Note that up to three characters prior to the comma character may be corrupted by the realignment process. The second K28.5 shows the case when a comma is detected and no phase adjustment is necessary. It illustrates the position of the SYNi pulse in relation to the comma character on RXi[0:9].

Loopback Operation Loopback operation is controlled by the PLUP (Parallel Loopback), SLPN (Serial Loopback) and LPNi inputs as shown in Table 2. LPNi enables PLUP/SLPN on a per-channel basis when LOW. If LPNi is HIGH, PLUP/SLPN have no impact on Channel x. When SLPN and PLUP are both HIGH the transmitter output is held HIGH. When RXx is looped back to TXx, the data goes through a clock recovery unit so much of the input jitter is removed. However, the TXx outputs may not meet jitter specifications listed in the "Transmitter AC Specifications" due to low frequency jitter transfer from RXx to TXx. Table 2: Loopback Selection LPNi

INPUT - TTL: TTL Reference Clock. This rising edge of RFCT provides the reference clock, at 1/10th or 1/20th of the baud rate (depending on RFCM) to the Clock Multiplying PLL. If RFCT is used, set RFC+ HIGH and leave RFC- open. If all TCi inputs are HIGH, the rising edge of RFCT will latch TXi[0:9] on all four channels INPUT - TTL: Reference Clock Mode Select. When LOW, RFC is at 1/20th of the transmit baud rate (i.e., 62.5MHz for 1.25Gb/s). When HIGH, RFC is at 1/10th the baud rate (i.e., 125MHz for 1.25Gb/s). OUTPUT - TTL: These are identical copies of the transmit baud rate clock divided by 10. INPUT - TTL: Per Channel Transmit Byte Clock for Channel x. All four channels' parallel TXi[0:9] inputs may be timed to RFC, TCC, or independently to TCi. Refer to the Serializer description. INPUT - TTL: Latch Transmit Byte Clocks. When LOW, internal PLLs align clocks with each of the transmit byte clocks, if present. Data may be corrupted when LOW. When HIGH, alignment will remain static regardless of actual TCi location.

PLUP
INPUT - TTL: Parallel Loopback Enable Input. RXi is input to the CRU for Channel x (normal operation) when PLUP is LOW. When HIGH, internal loopback paths from TXi to RXi are enabled. Refer to Table 2. INPUT - TTL: Serial Loopback Enable Input. Normal operation when HIGH. When LOW, SI+/- is looped back to TXi+/- internally for diagnostic purposes. Refer to Table 2 and related description. INPUT - TTL: Loopback Enable Pins. When LPNi is LOW, PLUP/SLPN impact Channel x. When HIGH, PLUP/SLPN have no effect on Channel x. INPUT - TTL: Enables SYNi and Word Alignment when HIGH. When LOW, keeps current word alignment and disables SYNi (always LOW). OUTPUT - TTL: Comma Detect for Channel x. This output goes HIGH for half of an RCi1 period to indicate that RXi[0:9] contains a "comma" character (`0011111XXX'). SYNi will go HIGH only during a cycle when RCi0 is rising. SYNi is enabled when SYNC is HIGH. ANALOG: Loop Filter capacitor for the Clock Multiply Unit. Typically 0.1F connected between CAP0 and CAP1. Amplitude is less than 3.3V.
