MK3721 Datasheet (Integrated Circuit Systems)

MK3721, Low Cost 3.3 Volt VCXO

The MK3721 is ICS/MicroClock’s lowest cost, low jitter, high performance 3.3 volt VCXO designed to replace expensive VCXO modules.

The 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 ICS/MicroClock’s patented VCXO
