Overview
The DS90CR215MTDX/NOPB, produced by Texas Instruments, is a 3.3V Rising Edge Data Strobe LVDS 21-Bit Channel Link transmitter. This component is part of the DS90CR215/DS90CR216 chipset, designed to convert 21 bits of CMOS/TTL data into three LVDS (Low Voltage Differential Signaling) data streams. It also transmits a phase-locked transmit clock in parallel with the data streams over a fourth LVDS link. This device is optimized for high-speed data transmission and cable reduction, making it suitable for various applications requiring reliable and efficient data transfer.
