ICS9169C-36
Low Cost 20-Pin Frequency Generator
Description
TheICS9169C-36generates the I/O clocks needed as a satellite
clock generator to a CPU and PCI clock source (such as the
ICS9148-01 or ICS9150-01). This device can generate the
audio Codec or DSP clocks if required (or Stop those outputs
Low).
The device is nominally driven at the X1 pin by a 14.31818
MHz clock source. The device can also be driven by a crystal
using external load capacitors as a stand-alone generator.
The SREF0 output is a reference clock output which is stronger
to allow multiple ISA slots.
Features
• Generator for periphary clock chips as companion
device to CPU/SDRAM/PCI generator.
• Accepts clock input at X1 pin or crystal across X1,
X2 pins as 14.31818 MHz nominal inputs.
• Three REF clock buffer outputs (SREF is Strong)
• Two 48MHz and one 24 MHz outputs
• Selectable audio clock generator with audio (Audio)
and half speed (Audio/2) outputs
• 20 pin (209 mil) SSOP package
