Overview

The MK3720 is a low cost, low jitter, high performance 3.3 Volt VCXO and PLL clock synthesizer designed to replace expensive 13.5, 27, or 54MHz VCXOs. The patented 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.

  • Packaged in 8 pin SOIC
  • 3.3 V only operating voltage
  • Output clocks of 54, 27, and 13.5MHz
  • Uses an inexpensive 13.500 MHz external crystal
  • On-chip patented VCXO with pull range of 200ppm (minimum)
  • VCXO tuning voltage of 0 to 3.3 V
  • 12 mA 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 MK3720A gives a wider pull range than the MK3720S, and so is recommended for all new designs, and cost reductions of existing designs.
