... DIFFERENTIAL SPREAD SPECTRUM CLOCK DRIVER Description The MK1493- spread-spectrum clock generator used as a companion chip with a CK410 system clock. The device is used 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 ...
