ISL34321 Datasheet | Renesas

16-Bit Long-Reach Video SERDES with Bi-directional Side-Channel FN6870 Rev 1.00 Jul 15, 2010 The ISL34321 is a serializer/deserializer of LVCMOS parallel video data. 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. It also transports auxiliary data bidirectionally over the same link during the video vertical retrace interval. I2C bus mastering allows the placement of external slave devices on the remote side of the link. An I2C controller can be place on either side of the link allowing bidirectional I2C munication through the link to the external devices on the other side. Both chips can be fully configured from a single controller or independently by local controllers. Applications- (see page 12) - Video entertainment systems - Industrial puting terminals - Remote cameras Features - 16-bit RGB transport over single differential pair - 6MHz to 45MHz pixel clock rates - Bi-directional auxiliary data transport without extra bandwidth and over the same differential pair - Hot plugging with automatic resynchronization every HSYNC. - I2C Bus Mastering to the remote side of the link with a controller on either the serializer or deserializer - Selectable clock edge for parallel data output - DC balanced with industry standard 8b/10b line code allows AC-coupling - Provides immunity against ground shifts - 16 programmable settings each for transmitter amplitude boost and pre-emphasis and receiver equalization allow for longer cable lengths and higher data rates - Same device for serializer and deserializer simplifies inventory Related Literature- (see page 12) - See ISL34341 datasheet FN6827 “WSVGA 24-Bit Long-Reach Video SERDES with Bi-directional Side-Channel” Typical Application 3.3V 1.8V VDD_IO 3.3V 1.8V VDD_IO VDD_TX VDD_AN VDD_IO VDD_P VDD_CR VDD_CDR...
