MK2705 Datasheet, PDF (1/6 Pages) Integrated Circuit Systems – Audio Clock Source

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
