Description
The MK1493-05 is a spread-spectrum clock generator used
as a companion chip with a CK410 system clock. The
device is used in a PC or embedded system to substantially
reduce electro-magnetic interference (EMI). The device
provides a differential spread-spectrum high frequency
output and a reference output clock. An SMBus is
connected to the CK410 for command and control of the
MK1493-05. The input reference clock to the MK1493-05
comes directly from the CK410. No external, expensive
crystal or crystal oscillator is required.
A 16-pin TSSOP package is employed to maximize board
space utilization.
Features
