DUAL OUTPUT 3.3 VOLT VCXO
MK3725
Description
The MK3725 is a low cost, high-performance, two
output 3.3 Volt VCXO and PLL clock synthesizer
designed to replace expensive VCXOs and crystals.
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 ±115 ppm minimum. Using
our analog Phase Locked Loop (PLL) techniques, the
device uses an external, fundamental mode pullable
crystal input to produce output clocks of 2x the input
frequency.
The frequency of the on-chip VCXO is adjusted by an
external control voltage input into pin VIN. Because
VIN is a high impedance input, it can be driven directly
from an PWM RC integrator circuit.
Features
