Additional Infomation About Product

DATASHEET DIFFERENTIAL SPREAD SPECTRUM CLOCK DRIVER MK1493-05 Description Features The MK1493-05 is a spread-spectrum clock generator used Packaged in 16-pin TSSOP package as a companion chip with a CK410 system clock. The Pb (lead) free package device is used in a PC or embedded system to substantially Single differential spread spectrum clock reduce electro-magnetic interference (EMI). The device Spread spectrum for EMI control provides a differential spread-spectrum high frequency Supports SMBUS index read/write and blocks read/write output and a reference output clock. An SMBus is operations connected to the CK410 for command and control of the Uses external 14.31818 MHz clock from CK410 MK1493-05. The input reference clock to the MK1493-05 Low output jitter design comes directly from the CK410. No external, expensive crystal or crystal oscillator is required. Power down mode lowers Idd Spread selection via hardware pins (down and center) A 16-pin TSSOP package is employed to maximize board Industrial temperature range available (-40C to +85C) space utilization.
