MK3725

Stresses above the ratings listed below can cause permanent damage to the MK3725. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.

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 MK3725 uses an external, fundamental mode pullable crystal input to produce output clocks of 2x the input frequency.

The frequency of the on-chip VCXO of MK3725 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.
