MK3754 - Low Cost 54 MHz 3.3 Volt VCXO

General 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.

Key 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.

I C R O C LOC K 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. The MK3754A is a drop-in replacement to the earlier MK3754S. MK3754 Low Cost 54 MHz 3.3 Volt VCXO Features • Packaged in 8 pin SOIC • 3.3 V only operating voltage • Uses an inexpensive 13.
