Description

27MHZ AND 54MHZ 3.3V VCXO
The MK3720DLFTR is a drop-in replacement for the MK3720S and MK3720A devices. Compared to these earlier devices, the MK3720D offers a wider operating frequency range and improved power supply noise rejection.

The MK3720DLFTR is a low cost, low jitter, high-performance 3.3 volt VCXO and PLL clock synthesizer designed to replace expensive 13.5, 27, or 54 MHz 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 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 MK3720DLFTR exhibits a moderate VCXO gain of 120 ppm/V typical, when used with a high-quality external pullable quartz crystal.

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.
