This standard provides the functional definition, ball-out configuration and package outline, signal definitions and input/output characteristics for a 28-bit 1:2 registered driver with parity suitable for use on DDR2 RDIMMs. The SSTU32865 integrates the functional equivalent of two SSTU32864 devices (as defined in JESD82-7) into a single device, thereby easing layout and board design constraints especially on high density RDIMMs such as dual rank, by four configurations. Moreover, the optional use of a parity function is provided for, permitting detection and reporting of parity errors across its 22 data inputs. JESD82-9 specifies a 160-pin Thin-profile, fine-pitch ball-grid array (TFBGA) package. This is a minor editorial revision as shown in Annex A of the document.

This standard defines standard specifications of dc interface parameters, switching parameters, and test loading for definition of the SSTU32866 registered buffer with parity test for DDR2 RDIMM applications. The purpose is to provide a standard for the SSTU32866 (see Note) logic device, for uniformity, multiplicity of sources, elimination of confusion, ease of device specification, and ease of use. This is a minor editorial revision as shown in Annex A of the document.
