isl59601, isl59602, isl 59603, isl59604, isl59605 20 fn6739.2 september 5, 2012 functional description megaq? overview megaq? is a fully automated, stand-alone equalizer for composite video transmitted over utp (unshielded twisted pair, i.e. cat 5, cat 6, etc.) or coaxial (rg-59) cables. differential video signals sent over long distances of twisted pair wire exhibit large high frequency attenuation, resulting in loss of high frequency detail/blurring. the exact loss characteristic is a complex function of wire gauge, length, composition, and coupling to adjacent conductors. the video signal can be restored by applying a filter with the exact inverse transfer function to the far end signal. megaq? is designed to compensate for the losses due to long cables, and incorporates the functionality an d flexibility to match a wide variety of cable types and loss characteristics. while megaq? was designed an d optimized for stand-alone operation, with no need for any external control of any kind, it has an optional spi serial interface with some additional features. see ?additional equalization modes available with the serial interface? on page 22 for more information on the features and operation of the serial interface. equalization for various cable types table 1. cable types and lengths cable type maximum length supported copper-core cat5/cat5e 5300 feet cat6 5600 feet coaxial - rg-59 6000 feet cat2/cat3 (telephone wire) 3000 feet belden imsa spec 39-2 581718 (3-pair traffic light cable) 5300 feet non-copper-core* cat5/cat5e cca (copper-coated aluminum core) 2000 feet coaxial - rg-59 ccs (copper-coated steel core) 1500 feet *image quality will be significantly improved over unequalized cable, but there will still be some image smearing due to the high resistance of the core material. figure 45. application circuit for utp cable 75.0 sd sen sck in- gnd gnd in+ out cfb v ref 1.0f 49.9 0.47f differential video input+ serial interface (optional) differential video input- 1k 0.047f v dd 1 v dd 2 0.1f internally generated +5v 300 invert eq_disable color locked freeze 1.0f 49.9 isl59601 isl59602 isl59603 isl59604 isl59605 ferrite bead ? dc resistance = 1 , 600 at 100mhz, 100ma dc current rating freezes eq once lock is achieved. tie freeze low if not used. 4.7f 0.1f 1500pf c1 c2 r1 r2 r3 c4 r5 c5 r6 video out c6 c7 c8 c9 5v tvs 5v tvs z1 z2 tvs = transient voltage suppressor a.k.a. transorb
isl59601, isl59602, isl 59603, isl59604, isl59605 21 fn6739.2 september 5, 2012 application information unshielded twisted pair (utp) app circuit figure 45 shows the complete schematic for a megaq? equalizer configured for unshielded twisted pair (utp) cable. the input signal is terminated into the network formed by r1, r2, and r3. c1 and c2 ac-couple the signal into megaq?. to protect the front-end circuitry, 5v transo rbs (z1 and z2) should be used instead of diodes because the signals on either differential input may swing far enough below ground to turn on a diode and distort the video. on the output side, c5, r5, and c4 form a compensation network, while r6 provides 75 ? source-termination for the video output. megaq? has an native gain of 6db, so when video out is terminated into 75 ? (the input to a dvr, tv, etc.), r6 and the 75 ? terminator form a 2:1 divider, producing standard video amplitude across the 75 ? terminator. coax input circuit figure 46 shows the input termination recommended for coaxial cables. the differential termination resistance is now 75 ? to match the characteristic impedanc e of the rg-59 coax cable. c3 bypasses high-frequency noise on the coax ground line to system ground. this allows the coax ground to be independent of the system at low frequencies (dc to 50/60hz) to accommodate differences in the ground potential of the remote video source(s). the coax startup network (d1, r4 , c4) prevents a rare start-up condition that can occur when a high average-picture-level (e.g. white screen) video signal is present on the inputs before the power has been applied. dual utp/coax input circuit if desired, it is also possible to support both utp and coax cables with the same pcb layout using two spst switches that are closed when in coax mode (figure 47). since utp requires a 100 ? termination network while coax requires 75 ? , a switch to introduce a shunt 300 ? resistor when in coax mode will change the termination from 100 ? to 75 ? . a second switch is required to engage c3. the addition of the coax startup circuit (d1, r4, c4) can unbalance the capacitance of the differential pair and degrade the cmrr in utp applicat ions. this in turn could cause excess noise at long lengths of ut p. in utp applications, if the output signal is too noisy at long distances, an optional capacitor cx may be used to balance the capacitance of the differential inputs. the value of cx should be determined by calculating how much trace capacitance is added by the coax startup circuit. a typical value for a good layout is ~5pf. note that only coax or utp should be connected at any one time - this circuit does not multiplex between them. input multiplexing placing a semiconductor multiplexer in front of this part may increase high frequency atte nuation and noise. however a low-capacitance mechanical relay may be acceptable. note that changing from one channel to another in lock until reset mode will require a reset (invert toggle) to trigger equalization of the new channel (see ?lock until reset? on page 21). for best performance, do not multiplex the inputs to the equalizer - this can further degrade the signal. instead, multiplex at the output after equalization has been performed. stand-alone operation and configuration in its default stand-alone config uration, megaq? features two modes of automatic cable equalization: lock until reset and continuous update . lock until reset is the recommended mode for most applications. lock until reset in the lock until reset mode, once megaq? finds the optimum equalization and the locked signal goes high, the equalization is frozen and will not change until either the power is cycled or the invert signal is toggled, wh ich initiates a re-equalization of the input signal. re-equalization is usually only necessary during device/system evaluation - in normal operation megaq? powers-up, acquires and equalizes the signal, and continues to equalize until/unless it is powered-down. if the signal is lost in lock until reset mode, the locked pin will not go low until/unless the device is reset by toggling the invert pin. a reset should only be necessary if the length or type of cable was changed without cycling power. to enable the lock until reset mode, tie the locked output pin to the freeze input pin as shown in figure 45 on page 20. to generate a reset (and trigge r a re-equalization), toggle the external invert pin to its oppo site state for at least 1ms. depending on the initial state of invert, this would be a high-low-high or low-high-low sequence. figure 46. application circuit for coax cable in- gnd in+ 1.0f 37.5 1k 1.0f 37.5 0.1f v cc 0.1f 10k megaq tm r1 r2 r3 c1 c2 c3 r4 c4 d1 5v tvs z2 z1 5v tvs tvs = transient voltage suppressor a.k.a. transorb coax figure 47. application circuit for utp/coax cable in- gnd in+ 1.0f 49.9 1k 1.0f 49.9 0.1f v cc 0.1f 10k megaq tm 300 close all switches for coax r1 r2 r3 c1 c2 c3 r4 c4 d1 sw1a r5 sw1b 5v tvs z2 z1 5v tvs utp in+ utp in- coax cx* *optional 5.6pf tvs = transient voltage suppressor a.k.a. transorb
isl59601, isl59602, isl 59603, isl59604, isl59605 22 fn6739.2 september 5, 2012 continuous update in the continuous update mode, megaq? will continuously try to find the optimum equalization solution. when the equalization has settled for 100 sequential vi deo lines with no changes, the locked pin will go high. however once lock is achieved, noise and average-picture-level changes may cause the device to unlock, causing some image perturbation while megaq? re-equalizes. the continuous update mode is enabled whenever the freeze pin is set to a logic low (grounded). polarity detection and correction megaq? features polarity detection and correction, automatically detecting incorrectly-wired input signals and inverting the signal inside the ic as necessary. the detected polarity is indicated by th e state of the invert pin. the invert pin has 2 modes of oper ation. it is typically used to indicate whether or not the incoming signal is inverted (the ?+? signal on the ?-? input and vice-versa). the state of the invert signal is then used to tell the signal processing logic whether or not to invert the signal in the signal path. a logic high on invert indicates that the positive differential input signal is on in- (pin 5) and the negative differential input signal is on in+ (pin 3). a logic low indicates nominal polarity. however the unique design of the invert i/o pin (figure 48) also allows megaq??s internal inversion detector to be overdriven externally, forcing megaq? to invert or not invert the signal regardless of the state of the inve rsion detection function. this is not necessary in normal oper ation, but it may improve performance in particularly noisy environments when the polarity of the signal is guaranteed to be correct. the color pin the color pin has 2 modes of operat ion. it is typically used to indicate whether or not the incoming signal has a colorburst or not. the state of the color signal is then used to tell the signal processing logic whether or not it can rely on the presence of a colorburst signal. a logic high in dicates a color signal; a logic low indicates monochrome. however the unique design of th e color i/o pin (figure 49) also allows megaq??s internal color detector to be overdriven externally. this is not necessary in normal operation, but it may improve performance in particularly noisy environments when the signal type is predetermined. monochrome video signals megaq? will equalize monochrome signals to the same distance as color signals. however due to the high level of noise past ~4800 feet, the color and locked indicators may become invalid for monochrome signals. the device will still equalize properly if this occurs. security cameras megaq? is ideal for security camera installations. the automatic adaptive equalizer doesn't need any active silicon on the transmit side of the cabl e, enabling upgrading of older installations without having to touch the installed camera base, including older monochrome cameras. megaq? automatically adjusts for wiring polarity errors as well as adjusts for optimum image qual ity. these features eliminates the need for the installer to make any adjustments. with an extended equalization range of 5300ft, the isl59605 enables cameras to be placed in even more remote locations, enabling coverage of up to three square miles from a single monitoring station. additional equalization modes available with the serial interface in addition to the lock until reset and continuous update modes, software control of megaq? through the spi interface adds a lock until signal loss mode and a manual equalization mode. note: when controlling megaq? th rough the spi interface, the external freeze pin must be tied to ground (logic low) . failure to keep freeze at a logic low will prevent the software controls from working properly. all of the equalization modes are selected via the two ?locking mode/manual length enable? register bits, 0x05[1:0]. continuous update continuous update mode is entered by setting address 0x05[1:0] = 00b. continuous update behavior is the same as described in the stand-alone mode. inversion detection logic 13k isl5960x signal processing invert pin figure 48. invert pin structure color detection logic 13k isl5960x signal processing color pin figure 49. color pin structure
isl59601, isl59602, isl 59603, isl59604, isl59605 23 fn6739.2 september 5, 2012 lock until reset lock until reset mode is entered by setting address 0x05[1:0] = 10b. lock until reset behavior is the same as described in the stand-alone mode, with the exception of how to generate a reset. to generate a reset via software, select continuous update mode and then return to lock until reset mode (register 0x05[1:0] = 00b then 10b). toggling invert (either the hardware pin or the software bit) will not cause a reset/re-equalization event. lock until signal loss lock until signal loss mode is entered by setting address 0x05[1:0] = 01b. lock until signal loss can only be enabled via the spi interface. in the lock until signal loss mode, megaq? will freeze the equalization once the locked pin goes high (in the same way as lock until reset ). unlike the ?settled? state in the continuous update mode, only a signal loss lasting more than 1ms (typical) will cause megaq? to re-equalize the si gnal when it returns. in this sense, the lock until signal loss mode can be considered as halfway between the continuous update mode and the lock until reset mode. the lock until signal loss mode is useful, for example, when testing or demonstrating a system by plugging in multiple different length cables - it eliminates the need to also generate a reset. to prevent potentially undesi red re-equalization, signal losses lasting less than 1ms (typical) do not trigger a re-equalization. manual length manual length mode is entered by setting address 0x05[1:0] = 11b. manual length mode allows the forcing of specific cable lengths, cable type, dc gains, etc. (see the register listing on the next page). the ?cable type? bit (0x05 [4]) allows selection between the two most co mmon cable types for security video: cat 5/6 or steel core rg-59 coaxial. however since many of megaq??s automatic functions and adjustments are disabled in manual length mode, performance is almost always worse than what is achieved in any of the automatic modes. for example, automatic polarity correcti on is disabled so the polarity must be manually set using the invert bit. there is no practical reason to ever use manual length mode in normal operation. serial interface protocol while megaq? is designed to work as a stand-alone equalizer, it does have a serial interface that can be used to control it and monitor its state. the serial interface is used to read and write the configuration registers. it uses three si gnals (sck, sd, and sen) for programming. the serial clock can operate up to 5mhz (5mbits/s). the ?serial timing diagram? on page 8 shows the timing of serial i/o. a transaction begins when the host microcontroller takes sen (serial enable) high. the first 8 bits on the sd (serial data) pin are latched by megaq? on the rising edge of sck (serial clock) to form the address byte. the msb of the address byte indicates whether the operation is a read (1) or a write (0), and the next seven bits indicate which register is to be read from or written to. each read and write operation cons ists of 16 bits: 8 bits for an address byte followed by 8 bits of data. see the ?serial timing diagram? on page 8 for more details on using the spi interface. write operation after the address byte is clocked in, the next 8 bits should contain the data to be sent to the register identified in the address byte. read operation after the rising edge of the 8th clock after the address byte is clocked in, the microcontroller should tristate th e sd line so megaq? can begin to output data on the sd pin (from the register identified in the address byte), beginning on the 9th rising edge of sck. the data should be latched on the falling edge of sck to allow enough time for the data to settle. see ??serial timing diagram? on page 8 for more details on how to read from the registers. table 2. address byte format 0 = write 1 = read a6 a5 a4 a3 a2 a1 a0 (msb) (lsb)
