SSTUB32866  
1.8 V 25-bit 1 : 1 or 14-bit 1 : 2 configurable registered buffer  
with parity for DDR2-800 RDIMM applications  
Rev. 04 — 15 April 2010  
Product data sheet  
1. General description  
The SSTUB32866 is a 1.8 V configurable register specifically designed for use on DDR2  
memory modules requiring a parity checking function. 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 SSTUB32866 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 SSTUB32866 is packaged in a 96-ball, 6 × 16 grid, 0.8 mm ball pitch LFBGA package  
(13.5 mm × 5.5 mm).  
2. Features and benefits  
„ Configurable register supporting DDR2 up to 800 MT/s Registered DIMM applications  
„ Configurable to 25-bit 1 : 1 mode or 14-bit 1 : 2 mode  
„ Controlled output impedance drivers enable optimal signal integrity and speed  
„ Meets or exceeds SSTUB32866 JEDEC standard speed performance  
„ Supports up to 450 MHz clock frequency of operation  
„ Optimized pinout for high-density DDR2 module design  
„ Chip-selects minimize power consumption by gating data outputs from changing state  
„ Supports SSTL_18 data inputs  
„ Checks parity on the DIMM-independent data inputs  
„ Partial parity output and input allows cascading of two SSTUB32866s for correct parity  
error processing  
„ Differential clock (CK and CK) inputs  
„ Supports LVCMOS switching levels on the control and RESET inputs  
„ Single 1.8 V supply operation (1.7 V to 2.0 V)  
„ Available in 96-ball, 13.5 mm × 5.5 mm, 0.8 mm ball pitch LFBGA package  
3. Applications  
„ 400 MT/s to 800 MT/s DDR2 registered DIMMs desiring parity checking functionality
