MK2705

Audio Clock Source

Description

The MK2705 provides synchronous clock generation

for audio sampling clock rates derived from an MPEG

stream, or can be used as a standalone clock source

with a 27 MHz crystal. The device uses the latest PLL

technology to provide good phase noise and long term

jitter characteristics in a small 8-pin package.

Contact ICS if you have a requirement for an input and

output frequency not included in this document.

Features

• Packaged in 8-pin (150 mil wide) SOIC

• Clock or crystal input

• Low phase noise

• Low jitter

• Exact (0 ppm) multiplication ratios

• Independent output voltage

• Support for 256 times sampling rate
