CAB4A Overview
The CAB4 is 32-bit 1:2 mand/Address/Control Buffer and 1:4 differential Clock Buffer designed for operation on DDR4 registered DIMMs with a 1.2 V VDD mode. All inputs are pseudo-differential using external or internal voltage reference. All outputs are full swing CMOS drivers optimized to drive 15 to 50 Ω effective terminated traces in DDR4 RDIMM, LRDIMM and 3DStacked DIMM applications.
