PRELIMINARY INFORMATION

ICS650-05

HDTV Clock Synthesizer

Description

The ICS650-05 is a low cost, low jitter, high

performance clock synthesizer designed to

produce 74.175824 MHz and 74.250000 MHz as

necessary for HDTV applications. Using our

patented analog Phase-Locked Loop (PLL)

techniques, the device uses a 27.0 MHz clock or

fundamental crystal input to produce buffered,

fixed clocks and a selectable frame rate clock for

HDTV systems.

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, dual 27.0 MHz, and

54.0 MHz output clocks with a selectable Frame

Rate Clock of 74.175824 MHz or

74.250000 MHz

• Ideal for HDTV applications

• 3.3 V or 5.0 V operating voltage
