DESCRIPTION

· The SSTUG32868 is a 1.8 V, 28-bit 1:2 register designed for high-density DDR2 memory modules, integrating the functionality of two JEDEC-standard registers into a single package.

· It includes a parity function for error detection and is permanently configured for high output drive strength, suitable for dense DIMM designs.

· Packaged in a 176-ball TFBGA, it optimizes board space and signal routing for high-density applications.

FEATURES

· Fully compliant with JEDEC standards for DDR2 registers.

· Supports 2 rank by 4 DIMM density by integrating the functionality of two standard DDR2 registers.

· Includes a parity checking function across 22 input data bits and a parity out signal.

· Features controlled multi-impedance output drivers for optimal signal integrity.

· Operates up to 450 MHz and is optimized for high-density DDR2 module designs.

· Chip-select inputs minimize power consumption by gating data outputs.

APPLICATIONS

· Ideal for use in high-density DDR2 memory modules, particularly in 2R×4 configurations.

· Suitable for applications requiring robust signal integrity and high-speed performance in densely populated memory modules.
