MK2732-05
Low Phase Noise VCXO+Multiplier
Description
The MK2732-05 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 14.318 MHz pullable crystal input to produce
one or two output clocks.
ICS manufactures the largest variety of Set-Top
Box and multimedia clock synthesizers for all
applications. Consult ICS to eliminate VCXOs,
crystals and oscillators from your board.
Features
• Packaged in 16 pin narrow SOIC
• Replaces a VCXO and multiplier
• Uses an inexpensive pullable crystal
• Output clocks up to 85 MHz
• 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 both clocks
• 25 mA output drive capability at TTL levels
• Advanced, low power, sub-micron CMOS process
• 5 V operating voltage for core, ability to run
output clocks at 3.3V or 5V
