SSTUH32865 - 1.8V 28-bit high output drive 1:2 registered buffer

General Description

The SSTUH32865 is a 1.8 V 28-bit high output drive 1:2 register specifically designed for use on two rank by four (2R × 4) and similar high-density Double Data Rate 2 (DDR2) memory modules.

Key Features

  • s 28-bit data register supporting DDR2 s Higher output drive strength version of SSTU32865 optimized for high-capacitive load nets s Fully compliant to JEDEC standard JESD82-9 s Supports 2 rank by 4 DIMM density by integrating equivalent functionality of two JEDEC-standard DDR2 registers (that is, 2 × SSTU32864 or 2 × SSTU32866) s Parity checking function across 22 input data bits s Parity out signal s Controlled output impedance drivers enable optimal signal integrity and speed s Exceeds JESD82.

SSTUH32865 1.8 V 28-bit high output drive 1:2 registered buffer with parity for DDR2 RDIMM applications Rev. 01 — 11 March 2005 Product data sheet 1. General description The SSTUH32865 is a 1.8 V 28-bit high output drive 1:2 register specifically designed for use on two rank by four (2R × 4) and similar high-density Double Data Rate 2 (DDR2) memory modules. It is similar in function to the JEDEC-standard 14-bit DDR2 register, but integrates the functionality of the normally required two registers in a single package, thereby freeing up board real-estate and facilitating routing to accommodate high-density Dual In-line Memory Module (DIMM) designs.
