Overview
The DS90CR287MTD/NOPB, produced by Texas Instruments, is a +3.3V Rising Edge Data Strobe LVDS 28-Bit Channel Link Transmitter. This device is designed to convert 28 bits of LVCMOS/LVTTL data into four LVDS (Low Voltage Differential Signaling) data streams, along with a phase-locked transmit clock transmitted in parallel over a fifth LVDS link. This chipset is ideal for solving EMI and cable size issues associated with high-speed TTL interfaces.
