描述

The MK3727H is a low-drive, low-cost, single-output 3.3V Voltage Controlled Crystal Oscillator (VCXO) and PLL clock synthesizer designed to replace expensive VCXOs and crystals. The patented on-chip VCXO accepts a 0V to 3.3V input voltage to cause the output clocks to vary by ±115ppm minimum. Using our analog Phase-Locked Loop (PLL) techniques, the devices use an external, fundamental mode 13.5MHz pullable crystal input to produce output clocks of 27MHz. 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 a PWM RC integrator circuit.
