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.

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.
