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.
I
2
C bus mastering allows the placement of external slave
devices on the remote side of the link. An I
2
C controller can
be placed on either side of the link allowing bi-directional I

C
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.
