Overview
MK1442/MK1443 SCSI and Ethernet Clock Source Description 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...
