CAB4AZNRR概述

CAB4A - DDR4寄存器32位1: 2的命令/地址/控制缓冲器和1:4差分时钟缓冲器 CAB4A - DDR4 Register 32-Bit 1:2 Command/Address/Control Buffer and 1:4 Differential Clock Buffer

The CAB4 is 32-bit 1:2 Command/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 3D-Stacked DIMM applications. The clock outputs, command/address outputs, control outputs, data buffer control outputs can be enabled in groups, and independently driven with different strengths to compensate for different DIMM net topologies. The DDR4 Register 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 if one of the input signals DCS[n:0]_n is driven LOW or it could be used to access device internal control registers when certain input conditions are met.

The device is characterized in the operating temperature range from –40°C to 95°C.
