Description
Features
The MK3720 is a low cost, low jitter, high
performance 3.3 Volt VCXO and PLL clock
synthesizer designed to replace expensive 13.5, 27,
or 54MHz VCXOs. The patented on-chip
Voltage Controlled Crystal Oscillator accepts a
0 to 3.3 V input voltage to cause the output clocks
to vary by ±100 ppm. Using our patented VCXO
and analog/digital Phase-Locked Loop (PLL)
techniques, the device uses an inexpensive external
13.5 MHz pullable crystal input to produce output
clocks of 13.5 MHz, 27 MHz, and 54 MHz .
The MK3720A is a drop-in replacement to the
earlier MK3720S.
Packaged in 8 pin SOIC
3.3 V only operating voltage
Output clocks of 54, 27, and 13.5MHz
Uses an inexpensive 13.500 MHz external crystal
On-chip patented VCXO with pull range
of 200ppm (minimum)
VCXO tuning voltage of 0 to 3.3 V
12 mA output drive capability at TTL levels
Advanced, low power, sub-micron CMOS process
The A version is the latest, manufactured in a smaller
geometry process. The MK3720A gives a wider pull
range than the MK3720S, and so is recommended
for all new designs, and cost reductions of existing
designs.
