General Description

The SSTUB32868 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 SSTUB32868 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).

Key Features

  • 28-bit data register supporting DDR2.
  • Supports 2 rank by 4 DIMM density by integrating equivalent functionality of two JEDEC-standard DDR2 registers (that is, 2 × SSTUA32864 or 2 × SSTUA32866).
  • Parity checking function across 22 input data bits.
  • Parity out signal.
  • Controlled multi-impedance output impedance drivers enable optimal signal integrity and speed.
  • Meets or exceeds SSTUB32868 JEDEC standard speed performance.
  • Supports up to.
