DIFFERENTIAL SPREAD SPECTRUM CLOCK DRIVER DATASHEET MK1493-05 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.

DIFFERENTIAL SPREAD SPECTRUM CLOCK DRIVER

DATASHEET

MK1493-05

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.
• Packaged in 16-pin TSSOP package
• Available in Pb lead free package
• Single differential spread spectrum clock
• Spread spectrum for EMI control
• Supports SMBUS index read/write and blocks read/write
operations
• Uses external MHz clock from CK410
• Low output jitter design
• Power down mode lowers Idd
• Spread selection via hardware pins down and center
• Industrial temperature range available -40°C to +85°C

NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01
