Overview
The DS90CR288AMTD/NOPB is a +3.3V Low Voltage Differential Signaling (LVDS) 28-bit receiver designed by Texas Instruments. This component is part of the DS90CR287/DS90CR288A chipset, which is optimized for high-speed data transmission with low electromagnetic interference (EMI). The receiver converts four LVDS data streams back into 28 bits of LVCMOS/LVTTL data, making it an ideal solution for applications requiring high data throughput and minimal signal degradation.
