16-Bit Long-Reach Video SERDES with Bi-directional
Side-Channel
ISL34321
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
