MK1449B  
Sound/SCSI+Fast Ethernet Clock  
Description  
Features  
• Packaged as 8 pin SOIC  
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.  
• For Fast Ethernet plus SCSI on computer  
motherboards  
• For AC97 sound on computer motherboards  
• Less than 1 ppm synthesis error  
• Input crystal frequency of 14.31818 MHz  
• Operating voltages of 3.0 to 5.5V  
• Available in industrial temperature  
• Full CMOS level outputs with 25mA drive  
capability at TTL levels  
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.  
• Ideal for oscillator replacement  
• Advanced, low power CMOS process
