PRELIMINARY INFORMATION

MK2732-06

Low Phase Noise VCXO+Multiplier

Features

Description

The MK2732-06 is a low cost, low jitter, high

performance VCXO and PLL clock synthesizer

designed to replace expensive discrete VCXOs

and multipliers. The on-chip Voltage Controlled

Crystal Oscillator (VCXO) accepts a 0 to 3 V

input voltage to cause the output clocks to vary by

±100 ppm. Using ICS/MicroClock’s patented

VCXO and analog Phase-Locked Loop (PLL)

techniques, the device uses an inexpensive 10 MHz

to 14 MHz pullable crystal input to produce up to

three output clocks.

• Packaged in 16 pin TSSOP

• For xDSL chipsets

• For MPEG 2 decoders

• Replaces a VCXO and multiplier

• Uses an inexpensive pullable crystal

• On-chip patented VCXO with pull range of

200 ppm (±100 ppm) minimum

• VCXO tuning voltage of 0 to 3 V

• Zero ppm synthesis error in all clocks

• Full CMOS output swings with 25 mA output

drive capability at TTL levels

ICS manufactures the largest variety of clocks for

Set-top boxes and Communications. Consult ICS

to eliminate VCXOs, crystals, oscillators and

buffers from your board.

• Advanced, low power, sub-micron CMOS process

• 5 V operating voltage for core, ability to run

output clocks at 3.3V or 5V for easy interface

• Available in commercial and industrial temperature

versions
