ICS650-12

MPEG Clock Synthesizer

Description

The ICS650-12 is a low cost, low jitter, high

performance clock synthesizer designed to

produce fixed clock outputs of 13.5 MHz and

27.0 MHz and four selectable clock outputs of two

Processor Clocks (PCLK1 and PCLK2), Audio

Clock (ACLK), and Communications Clock

(CCLK). Using our patented analog Phase-

Locked Loop (PLL) techniques, the device uses a

27.0 MHz clock or fundamental crystal input to

produce clocks ideal for Digital Video/MPEG-

based applications.

Features

• Packaged in 20 pin tiny SSOP (QSOP)

• Input Frequency of 27.0 MHz

• Zero ppm synthesis error in output clocks

• Provides fixed 13.5 MHz and 27.0 MHz.

Also provides two selectable Processor Clocks,

one Audio Clock, and one Communications Clock

• Ideal for Digital Video/MPEG-based applications

• 3.3 V or 5.0 V operating voltage

• Entire chip powers down (when CS1=CS0=0)
