ICS9169C-36

www.DataSheet4U.com Integrated Circuit Systems, Inc. ICS9169C-36 Low Cost 20-Pin Frequency Generator Description 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. 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 Block Diagram Pin Configuration DataSheet4U.com DataShee 20-Pin SSOP Functionality 3.3V±10%, 0-70°C Clock source driving X1 pin or crystal (X1, X2) = 14.31818 MHz (all frequencies in MHz) FS1 FS0 AUDIO AUDIO/2 SREF, REF 48 MHz 24 MHz OE 0 1 All Outputs Tristate Active 0 0 1 1 0 1 0 1 XTAL/2 24.5795 33.8680 LOW XTAL/4 12.2898 16.9340 LOW 14.318 14.318 14.318 14.318 XTAL/2 48.008 48.008 48.008 XTAL/4 24.004 24.004 24.004 DataSheet4U.com ICS9169C-36RevD060197...
