M88DDR4RCD01 is a configurable 32-bit 1:2 Registering Clock Driver (RCD) with parity for DDR4 RDIMM and LRDIMM applications. The device supports 1.2 V VDD operations. The command, address and control bus inputs are pseudo-differential with an external or internal voltage reference. The outputs of these signals are full swing CMOS drivers optimized to drive single terminated 25..50 Ohms traces in DDR4 RDIMM and LRDIMM applications. The clock outputs Yn_t and Yn_c and control net outputs QxCKEn, QxCSn and QxODTn can be driven with a different strength to compensate for different DIMM net topologies. By disabling unused outputs the power consumption is reduced.
M88DDR4RCD01 operates from a differential clock (CK_t and CK_c). Inputs are registered at the crossing of CK_t going HIGH, and CK_c going LOW. The input signals could be either re-driven to the outputs or they could be used to access device internal control registers when certain input conditions are met.
