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.
