General Description
The V385 transmitter converts 28 bits of 3.3 V
CMOS/TTL into 4 Low Voltage Differential Signaling
(LVDS) data streams while the transmit clock input is
transmitted in parallel with the data streams over a fifth
LVDS link. The V385 can be programmed for rising
edge or falling edge clocks through pin R_FB.
ICS manufactures a large variety of video application
devices. Consult ICS for all of your video application
requirements.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the V385. These ratings, which are
standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at
these or any other conditions above those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical
parameters are guaranteed only over the recommended operating temperature range.
