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.
ICS reserves the right to make changes in the device data identified in this publication
without further notice. ICS advises its customers to obtain the latest version of all
device data to verify that any information being relied upon by the customer is current
and accurate.
