Manufacturer Part Number
ics9169c-36
Description
Cost 20-pin Frequency Generator
Manufacturer
ETC-unknow
Datasheet
Functionality
3.3V±10%, 0-70
Clock source driving X1 pin or crystal (X1, X2) = 14.31818 MHz
(all frequencies in MHz)
The ICS9169C-36 generates 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.
