Description

The MK3754 is ICS/Microclock’s 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/Microclock’s 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.

Features

? Packaged in 8 pin SOIC

? 3.3 V only operating voltage

? Uses an inexpensive 13.500 MHz external crystal

? On-chip VCXO (patented) with pull range of 200ppm (minimum)

? VCXO tuning voltage of 0 to 3.3 V

? 12mA output drive capability at TTL levels

? Advanced, low power, sub-micron CMOS process

? The A version is the latest, manufactured in a smaller geometry process. The MK3754A gives a wider pull range than the MK3754S, and so is recommended for all new designs, and cost reductions of existing designs.
