isl76322 10 august 15, 2011 fn7611.1 applications detailed description and operation a pair of isl76322 serdes transports 16-bit parallel video for the isl76322 along with auxilia ry data over a single 100 differential cable either to a di splay or from a camera. auxiliary data is transferred in both directions every video frame. this feature can be used for remote configuration and telemetry. the benefits include lower emi, lower costs, greater reliability and space savings. the same device ca n be configured to be either a serializer or deserializ er by setting one pin (video_tx), simplifying inventory. rgba/c, vsync, hsync, and dataen pins are inputs in serializer mode and outputs in deserializer mode. the video data presented to the serializer on the parallel lvcmos bus is serialized into a high-speed differential signal. this differential signal is converted back to parallel video at the remote end by the deserializer. the side channel data (auxiliary data) is transferred between the serdes pair during the first two lines of the vertical video blanking interval. when the side-channel is enabled, which is the default, there will be a number of pclk cycles uncertainty from frame-to-frame. this should not cause sync problems with most displays as this occurs during the vertical front porch of the blanking period. when properly configured, the serdes link supports end-to-end transport with fewer than one error in 10 10 bits. differential signals and termination the isl76322 serializes the 16-bit parallel data plus 3 sync signals at 20x the pclk_in frequency. the extra 2 bits per word come from the 8b/10b encoding scheme which helps create the highest quality serial link. the high bit rate of the differential serial data requires special care in the layout of traces on pcbs, in the choice and assembly of connectors, and in the cables themselves. pcb traces need to be adjacent, matched in length and drawn to result in a differential 100 ? controlled impedance. for best emi performance, the cable should be low loss and have a differential 100 ? impedance. the maximum cable length for a functioning link is dependent on the pclk_i n frequency, the cable loss and impedance, as well as the pr e-emphasis and equalization settings. functioning links of 25 meters are often possible at the maximum frequency. seriop and serion pins incorp orate internal differential termination of the se rial signal lines. serio pin ac-coupling ac-coupling minimizes the effects of dc common mode voltage difference and local power supply variations between two serdes. the serializer outputs dc balanced 8b/10b line code, which allows ac-coupling. the ac-coupling capacitor on serio pins must be 27nf on the serializer board and 27nf on the de serializer board. the value of the ac-coupling capacitor is very critical since a value too small will attenuate the high-speed signal at low clock rate. a value too big will slow down the turn around time for the side-channel. it is an advantage to have the pair of capacitors as closely matched as possible. receiver reference clock (ref_clk) the reference clock (ref_clk) for the pll is fed into pclk_in pin. ref_clk is used to recover the clock from the high-speed serial stream. ref_clk is very se nsitive to any instability. the following conditions must be met at all times after power is applied to the deserializer, or else the deserializer may need a manual reset: ? vdd must be applied and stable ? ref_clk frequency must be within the limits specified ? ref_clk amplitude must be stable a simple 3.3v cmos crystal oscillator can be used for ref_clk power supply sequencing the 3.3v supply must be higher than the 1.8v supply at all times, including during power-up and power-down. to meet this requirement, the 3.3v supply must be powered up before the 1.8v supply. for the deserializer, ref_clk must not be applied before the device is fully powered up. applying ref_clk before power-up may require the deserializer to be manually reset. a 10ms delay after the 1.8v supply is powered up guarantees normal operation. power supply bypassing and layout the serializer and deserializer functions rely on the stable functioning of plls locked to local reference sources or locked to an incoming signal. it is important that the various supplies (vdd_p, vdd_an, vdd_cdr, vdd_tx) be well bypassed over a wide range of frequencies, from below the typical loop bandwidth of the pll to approaching the signal bit rate of the serial data. a combination of different values of capacitors from 1000pf to 5f or more with low esr characteristics is generally required. the parallel lvcmos vdd_io supply is inherently less sensitive, but since the rgb and sync/datae n signals can all swing on the same clock edge, the current in these pins, and the corresponding gnd pins, can unde rgo substantial current flow changes. once again, a combination of different values of capacitors over a wide range, with low esr characteristics, is desirable. a set of arrangements of this type is shown in figure 5, where each supply is bypassed with a ferrite-bead-based choke, and a range of capacitors. a ?choke? is preferable to an ?inductor? in this application, since a high-q in ductor will be likely to cause one or more resonances with the shunt capacitors, potentially causing problems at or near those frequencies, while a ?lossy? choke will reflect a high impedance over a wide frequency range. the higher value capacitor, in particular, needs to be chosen carefully, with special care regarding its esr. very good results can be obtained with multilayer ceramic capacitors (available from many suppliers) and generally in small outlines (such as the 1210 outline suggested in the schematic shown in figure 5), which provide good bypass capabilities down to a few m at 1mhz to 2mhz. other capacitor technologies may also be
isl76322 11 august 15, 2011 fn7611.1 suitable (perhaps niobium oxide), but ?classic? electrolytic capacitors frequently have esr values of above 1 , that nullify any decoupling effect above the 1khz to 10khz frequency range. capacitors of 0.1f offer low impedance in the 10mhz to 20mhz region, and 1000pf capacitors in the 100mhz to 200mhz region. in general, one of the lower value capacitors should be used at each supply pin on the ic. figure 5 shows the grounding of the various capacitors to the pin corresponding to the supply pin. although all the ground supplies ar e tied together, the pcb layout should be arranged to emulate th is arrangement (at least for the smaller value (high frequency) capacitors), as much as possible. i 2 c interface the i 2 c interface allows access to internal registers used to configure the serdes and to obtain status information. a serializer must be assigned a different addr ess than its deserializer counterpart if the side channel is used. the upper 5 bits are permanently set to 011 11 and the lower 2 bits determined by pins as follows: thus, 4 serdes can reside on the same bus. by convention, when all address pins are tied low, the device address is referred to as 0x78. scl and sda are open drain to allow multiple devices to share the bus. if not used, scl and sda should be tied to vdd_io. exposed pad while it is not a required electrical connection, it is recommended that the exposed pad on the bottom of the package be soldered to the circuit board. this will ensure that the full power dissipation of the package can be utilized. the pad should be connected to ground and not left floating. for best thermal conductivity, 16 vias should connect the footprint for the exposed pad on the circuit board to the ground plane. this connection is not required for basic operation of the chip. figure 5. power supply bypassing 10f 10f 10f 10f 10f 10f 120 ? 120 ? 120 ? 120 ? 120 ? 120 ? 0.1f 0.1f 0.1f 0.1f 0.1f 0.1f 01111i2ca1i2ca0r/w figure 6. layout for the exposed pad copper pad vias 16x
