General Description

The FIN3385 and FIN3383 transform 28 bit wide parallel LVTTL (Low Voltage TTL) data into 4 serial LVDS (Low Voltage Differential Signaling) data streams. A phaselocked transmit clock is transmitted in parallel with the data stream over a separate LVDS link. Every cycle of transmit clock 28 bits of input LVTTL data are sampled and transmitted.
