V385A
8-BIT LVDS TRANSMITTER FOR VIDEO
General Description
The V385A 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.
Compared to the V385, the V385A provides an
extended clock frequency range of 12-90 MHz, rather
than 20-85 MHz. Other performance improvements
have been incorporated as well.
The V385A can be programmed for rising edge or
falling edge clocks through pin R_FB.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the V385A. 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.
