Data Sheet June 23, 2008

WSVGA 24-Bit Long-Reach Video SERDES with Bidirectional Side-Channel

The ISL34340 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.

ISL34340INZ* ISL34340INZ -40 to +85 64 Ld EPTQFP Q64.10x10B *Add “-T13” suffix for tape and reel. Please refer to TB347 for details on

reel specifications. NOTE: These Intersil Pb-free plastic packaged products employ special

Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
