1. General description
2. Features
The SSTUH32866 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 JESD82-7 standard for the SSTU32864 registered buffer, while adding the parity
checking function in a compatible pinout. The JEDEC standard for SSTUH32866 is
pending publication. 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 SSTUH32866 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 SSTUH32866 is packaged in a 96-ball, 6
package (13.5 mm
The SSTUH32866 is identical to SSTU32866 in function and performance, with
higher-drive outputs optimized to drive heavy load nets (for example, stacked DRAMs)
while maintaining speed and signal integrity.

... 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 SSTUH32866 must ensure that the outputs will remain LOW, thus ensuring no glitches on the output. ...
