MK1449B Sound/SCSI+Fast Ethernet Clock 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.
The device can accept either a crystal or clock input.
Also on the chip is the ability to generate a 1.
25x clock of the reference plus the reference, making it possible to generate 20 and 25 MHz clocks from a 20 MHz crystal.
Features • Packaged as 8 pin SOIC • For Fast Ethernet plus SCSI on computer motherboards • For AC97 sound on...
