MK1449B Overview
Description
The MK1449B is the most cost effective way to generate high quality, high frequency clock outputs for SCSI plus Fast Ethernet devices, or AC97 sound chips. Using Phase-Locked-Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive 14.31818 MHz crystal or clock to produce two output clocks.
