SSTUG32866EC/G,518 2. Features

The SSTUG32866 is a 1.8 V configurable register specifically designed for use on DDR2memory modules requiring a parity checking function. It is defined in accordance with theJEDEC standard for the SSTUG32866 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 inthe latter configuration can be designated as Register A or Register B on the DIMM.The SSTUG32866 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-inputsand 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 evennumber of ones across the DIMM-independent data inputs combined with the parity inputbit.The SSTUG32866 is packaged in a 96-ball, 6 · 16 grid, 0.8 mm ball pitch LFBGApackage (13.5 mm · 5.5 mm).n Configurable register supporting DDR2 up to 800 MT/s Registered DIMM applicationsn Configurable to 25-bit 1 : 1 mode or 14-bit 1 : 2 moden Controlled output impedance drivers enable optimal signal integrity and speedn Meets or exceeds SSTUG32866 JEDEC standard speed performancen Supports up to 550 MHz clock frequency of operationn Optimized pinout for high-density DDR2 module designn Chip-selects minimize power consumption by gating data outputs from changing staten Supports SSTL_18 data inputsn Checks parity on the DIMM-independent data inputsn Partial parity output and input allows cascading of two SSTUG32866s for correct parityerror processingn Differential clock (CK and CK) inputsn Supports LVCMOS switching levels on the control and RESET inputsn Single 1.8 V supply operation (1.7 V to 2.0 V)n Available in 96-ball, 13.5 mm · 5.5 mm, 0.8 mm ball pitch LFBGA package
