Functional Description
The ASM2I2318ANZ is a 3.3V buffer designed to distribute
high-speed clocks in PC applications. The part has 18
outputs, 16 of which can be used to drive up to four
SDRAM DIMMs, and the remaining can be used for
external feedback to a PLL. The device operates at 3.3V
and outputs can run up to 133MHz, thus making it
compatible
with
Pentium
ASM2I2318ANZ can be used in conjunction with the clock
synthesizer for a complete Pentium II motherboard
solution. The ASM2I2318ANZ also includes a serial
interface which can enable or disable each output clock.
On power-up, all output clocks are enabled (internal pull
up). A separate Output Enable pin facilitates testing on
ATE.
