SSTUH32865 - NXP

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

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 .

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 JESD82-9 speed performance (1.8 ns max. single-bit switching propagation delay, 2.0 ns max. mass-switching.
