M88DR5CK01 (Gen1 DDR5 CKD)

M88DR5CK01 is Montage's 1st-generation DDR5 Clock Driver (CKD) chip for use in the client memory to enhance the speed and stability of memory data access, matching the ever-increasing CPU operating speed and performance. The chip is compliant with the JEDEC DDR5CKD01 specification and supports data rates up to 7200MT/s. It supports double-sided bus address access and I²C, I3C interfaces. By configuring register control words, the chip can change its output signal characteristics to match the network topology of different DIMMs, and unused output signals can be disabled to reduce power consumption.
