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 communication 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 computing 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
