1. General description
2. Features
The SSTUM32866 is a 1.8 V configurable register specifically designed for use on DDR2
memory modules requiring a parity checking function. It is defined in accordance with the
JEDEC standard for the SSTUM32866 registered buffer. The register is configurable
(using configuration pins C0 and C1) to two topologies: 25-bit 1 : 1 or 14-bit 1 : 2, and in
the latter configuration can be designated as Register A or Register B on the DIMM.
The SSTUM32866 accepts a parity bit from the memory controller on its parity bit
(PAR_IN) input, compares it with the data received on the DIMM-independent D-inputs
and indicates whether a parity error has occurred on its open-drain QERR pin
(active LOW). The convention is even parity, that is, valid parity is defined as an even
number of ones across the DIMM-independent data inputs combined with the parity input
bit.
The SSTUM32866 is the high-output drive version of SSTUG32866.
The SSTUM32866 is packaged in a 96-ball, 6
package (13.5 mm

... As long as the data inputs are LOW, and the clock is stable during the time from the LOW-to-HIGH transition of RESET until the input receivers are fully enabled, the design of the SSTUM32866 must ensure that the outputs will remain LOW, thus ensuring no glitches on the output. ...
