DS90CR288 Datasheet +3.3V Rising Edge Data Strobe LVDS

Manufacturer: National Semiconductor (now Texas Instruments)

General Description

The DS90CR287 (see DS90CR287/288A datasheet) transmitter converts 28 bits of CMOS/TTL data into four LVDS (Low Voltage Differential Signaling) data streams.

A phaselocked transmit clock is transmitted in parallel with the data streams over a fifth LVDS link.

Every cycle of the transmit clock 28 bits of input data are sampled and transmitted.
