MK2761A

SET-TOP CLOCK SOURCE

Description

Features

The MK2761A is a low-cost, low-jitter,

• Packaged in a 16-pin narrow (150 mil) SOIC

• Available in Pb (lead) free package

high-performance clock synthesizer for set-top box

applications. Using analog Phase-Locked Loop (PLL)

techniques, the device accepts a 27 MHz crystal or

clock input to produce multiple output clocks including

the processor clock, the UART clock, a selectable

audio clock, and four low skew copies of the 27 MHz.

The audio clocks are frequency-locked to the 27 MHz

using our patented zero ppm error techniques. This

allows audio and video to track exactly, thereby

eliminating the need for large buffer memory.

• Selectable audio sampling frequencies support 32,

44.1, and 48 kHz in most DACs

• 27 MHz crystal or clock input

• Processor frequency of 16.67 MHz

• Fixed clocks of 27 and 3.6864 MHz

• Zero ppm in audio clocks exactly track video

frequency

• 25 mA output drive capability at TTL levels

• Advanced, low-power, sub-micron CMOS process

• Operating voltage of 5.0 V 10%

ICS manufactures a large variety of Set-top Box and

multimedia clock synthesizers for all applications.

Consult ICS to eliminate crystals and oscillators from

your board.
