Overview
The DS90CR288AMTDX is a 3.3V Rising Edge Data Strobe LVDS 28-Bit Channel Link Receiver produced by Texas Instruments, although it is often distributed under the National Semiconductor brand. This component is part of the DS90CR287/DS90CR288A family and is designed to convert four LVDS (Low Voltage Differential Signaling) data streams back into 28 bits of LVCMOS/LVTTL data. It also includes a phase-locked transmit clock that is transmitted in parallel with the data streams over a fifth LVDS link.
This receiver is optimized for high-speed data transmission and is suitable for applications requiring low power consumption and minimal cable size.
