RHFLVDS218：Rad-Hard LVDS Deserializer

The RHFLVDS218 deserializer converts the three LVDS data streams back into 21 bits of CMOS/TTL data. At a transmitter clock frequency of 75 MHz, 21 bits of TTL data are transmitted at a rate of 525 Mbps per LVDS data channel. Using a 75 MHz clock, the data throughput is 1.575 Gbit/s (197 Mbytes/s).

The RHFLVDS218 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 are high impedance when V_CC is tied to 0 V.
