1.8 V 28-bit 1:2 registered buffer with parity for DDR2 RDIMM  
applications  
Rev. 02 — 28 September 2004  
Product data sheet  
1. General description  
The SSTU32865 is a 1.8 V 28-bit 1:2 register specifically designed for use on two rank by  
four (2R × 4) and similar high-density Double Data Rate 2 (DDR2) memory modules. It is  
similar in function to the JEDEC-standard 14-bit DDR2 register, but integrates the  
functionality of the normally required two registers in a single package, thereby freeing up  
board real-estate and facilitating routing to accommodate high-density Dual In-line  
Memory Module (DIMM) designs.  
The SSTU32865 also integrates a parity function, which accepts a parity bit from the  
memory controller, compares it with the data received on the D-inputs and indicates  
whether a parity error has occurred on its open-drain PTYERR pin (active-LOW).  
The SSTU32865 is packaged in a 160-ball, 12 × 18 grid, 0.65 mm ball pitch, thin profile  
fine-pitch ball grid array (TFBGA) package, which—while requiring a minimum  
9 mm × 13 mm of board space—allows for adequate signal routing and escape using  
conventional card technology.  
2. Features  
28-bit data register supporting DDR2  
Fully compliant to JEDEC standard JESD82-9  
Supports 2 rank by 4 DIMM density by integrating equivalent functionality of two  
JEDEC-standard DDR2 registers (i.e. 2 × SSTU32864 or 2 × SSTU32866)  
Parity checking function across 22 input data bits  
Parity out signal  
Controlled output impedance drivers enable optimal signal integrity and speed  
Exceeds JESD82-9 speed performance (1.8 ns max. single-bit switching propagation  
delay, 2.0 ns max. mass-switching)  
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 Stub Series Terminated Logic SSTL_18 data inputs  
Differential clock (CK and CK) inputs  
Supports Low Voltage Complementary Metal Oxide Semiconductor (LVCMOS)  
switching levels on the control and RESET inputs  
Single 1.8 V supply operation  
Available in 160-ball 9 mm × 13 mm, 0.65 mm ball pitch TFBGA package
