Description

The MK3715 is a low 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’ patented VCXO techniques, the device uses an inexpensive external 13.5 MHz pullable crystal to produce two fixed clock outputs of 54.0 MHz and 108.0 MHz.
