W40S01-04 Datasheet (Cypress Semiconductor) - SDRAM Buffer

W40S01-04, SDRAM Buffer - 4 DIMM

SDRAM Outputs: Provides buffered copy of BUF_IN.

The propagation delay from a rising input edge to a rising output edge is 1 to 5 ns.

All outputs are skew controlled to within ± 250 ps of each other.

BUF_IN SDATA SCLOCK VDDQ3 I I/O I P Clock Input: This clock input has an input threshold voltage

W40S01-04 Features

* Eighteen skew controlled CMOS outputs (SDRAM0:17)

* Supports four SDRAM DIMMs

* Ideal for high-performance systems designed around Intel®’s 440BX chip set

* I2C serial configuration interface

* Output skew between any two outputs is less than 250 ps
