LOW DRIVE 3.3 VOLT VCXO
MK3727H
Description
The MK3727H is a low drive, low cost, single output 3.3
Volt VCXO and PLL clock synthesizers 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 devices uses an
external, fundamental mode 13.5 MHz pullable crystal
input to produce output clocks of 27 MHz. The drive
parameters are optimized for low EMI.
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.
