The UT54LVDS217 Serializer converts 21 bits of CMOS/TTL data into three LVDS (Low Voltage Differential Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams over a fourth LVDS link. Every cycle of the transmit clock 21 bits of input data are sampled and transmitted. At a transmit clock frequency of 75MHz, 21 bits of TTL data are transmitted at a rate of 525 Mbps per LVDS data channel and data throughput is 1.575 Gbit/s (197 Mbytes/sec).

The UT54LVDS217 Serializer allows the use of wide, high speed TTL interfaces while reducing overall EMI and cable size.
All pins have Cold Spare buffers. These buffers will be high impedance when VDD is tied to VSS.
