V385
8-BIT LVDS TRANSMITTER FOR VIDEO
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.
