DATASHEET
PCI CLOCK GENERATOR
MK1493-01
IDT / ICS PCI CLOCK GENERATOR
1
MK1493-01
REV B 021204
Description
The MK1493-01 is a general purpose clock generator part
that provides an integrated clocking solution for
PCI/networking applications. It provides 8 individually
programmable PCI clocks, 2 CPU clocks, additional fixed
PCI clocks and a 25 MHz reference clock for LAN support.
This part incorporates ICS’s newest clock technology,
offering more robust features and functionality. Using a
serially programmable SMBus interface, the MK1493-01
can select the output clock frequency, and
enabling/disabling each individual output clock.
Features
8 PCI clocks at 25, 33, 50, 66.66 MHz individually pin
selectable and serial port selectable
2 CPU clocks at 100 MHz
2 PCI clocks at 66.66 MHz
1 PCI clock @ 50 MHz
25 MHz reference clock
SMBus Programming
Power-up default frequency can be selected through FS
inputs
25 MHz crystal or clock input required
PCICLK cycle to cycle jitter <250ps
CPUCLK cycle to cycle jitter <100ps
Packaged in 48-pin (240mil) TSSOP Package
Operating Voltage 3.3V + - 5%
