ICSSSTUAF32868B Datasheet (IDT) - 28-BIT CONFIGURABLE REGISTERED BUFFER

ICSSSTUAF32868B, 28-BIT CONFIGURABLE REGISTERED BUFFER

This 28-bit 1:2 configurable registered buffer is designed for 1.7V to 1.9V VDD operation.

All inputs are compatible with the JEDEC standard for SSTL_18, except the chip-select gate-enable (CSGEN), control (C), and reset (RESET) inputs, which are LVCMOS.

All outputs are edge-controlled circuits opti

The convention is even parity, i.e., valid parity is defined as an even number of ones across the DIMM-independent data inputs combined with the parity input bit.

To calculate parity, all DIMM-independent D-inputs must be tied to a known logic state.

If an error occurs and the QERR output is driven low, it stays latched low for a minimum of two clock cycles or until RESET is dri
