LOW COST 54 MHZ 3.3 VOLT VCXO DATASHEET MK3754 Description The MK3754D and MK3754B are drop-in replacements for the MK3754S device. Compared to these earlier devices the MK3754D and MK3754B offer a wider operating frequency range and improved power supply noise rejection. The MK3754 is ICS’ lowest cost, low jitter, high performance 3.3 Volt VCXO and PLL clock synthesizer designed to replace expensive 54 MHz VCXOs. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3.3 V input voltage to vary the output clocks by ±100 ppm. Using ICS’ patented VCXO and analog/digital Phase-Locked Loop (PLL) techniques, the device uses an inexpensive external 13.5 MHz pullable crystal input to produce a 54 MHz output clock.
