MK3722

Stresses above the ratings listed below can cause permanent damage to the MK3722. 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 MK3722 is a low cost, low jitter, high performance VCXO and PLL clock synthesizer designed to replace expensive discrete VCXOs and multipliers. 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. Using ICS' analog/digital Phase-Locked Loop (PLL) techniques, the MK3722 uses an inexpensive 27 MHz pullable crystal input to produce a reference output and a selectable audio clock.

ICS MK3722 manufactures the largest variety of VCXO based timing devices for all applications. Consult ICS to eliminate VCXOs, crystals, and oscillators from your board.

The frequency of the on-chip VCXO of MK3722 is adjusted by an external control voltage connected to VIN. Because VIN is a high impedance input, it can be driven directly from an PWM RC integrator circuit.
