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.
