MK1442/MK1443
SCSI and Ethernet Clock Source
MDS 1442/3 F

The MK1442/3 are the ideal way to generate clocks for
desktop computer motherboards and LAN
workstations. Using analog Phase-Locked Loop (PLL)
techniques, the devices accept a
14.318 MHz crystal input to produce multiple output
clocks up to 100 MHz. They provide 2XCPU, CPU,
floppy controller, keyboard, system, SCSI and
Ethernet clocks. The MK1442/3 are perfect for new
Pentium Processor, PCI bus and 486 systems. The
devices can operate at 5V or 3.3V up to and including
80MHz on the CPU clock.
The devices are identical except the MK1442 has an
Output Enable (OE) pin that tri-states all outputs when
taken low, and the MK1443 has an extra 14.318 MHz
clock.
