Supports four SDRAM DIMMs
Ideal for high-performance systems designed around
Intel’s 440BX chip set
I
2
C serial configuration interface
Output skew between any two outputs is less than
250 ps
1 to 5 ns propagation delay
DC to 133-MHz operation
Single 3.3V supply voltage
Low power CMOS design packaged in a 48-pin SSOP
(Small Shrink Outline Package)
Overview
The Cypress W40S01-04 is a low-voltage, eighteen-output
signal buffer. Output buffer impedance is approximately 15
which is ideal for driving SDRAM DIMMs.
