The UT54LVDS218 Deserializer converts the three LVDS data streams back into 21 bits of CMOS/TTL data. At a transmit clock frequency of 75MHz, 21 bits of TTL data are transmitted at a rate of 525Mbps per LVDS data channel and data throughput is 1.575 Gbit/s (197 Mbytes/sec).

The UT54LVDS218 Deserializer 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.
