RHFLVDS217:Rad-Hard LVDS Serializer

The RHFLVDS217 serializer converts 21 bits of CMOS/TTL data into three LVDS (low voltage differential signaling) data streams. A phase-locked transmitter clock is transmitted in parallel with the data streams over a fourth LVDS link. With every cycle of the transmitter clock, 21 bits of input data are sampled and transmitted.

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 RHFLVDS217 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 are high impedance when VCC is tied to 0 V.
