ISL34341
WSVGA 24-Bit Long-Reach Video
SERDES with Bi-directional Side-Channel
The ISL34341 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 bi-directionally 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 placed on either side of the link allowing bi-directional 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.

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.
