MK2727 - Low Cost 27 MHz VCXO

General Description

The MK2727 is MicroClock’s lowest cost, low jitter, high performance VCXO and PLL clock synthesizer designed to replace expensive 27MHz VCXOs.

The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3V input voltage to cause the output clocks to vary by ±100 ppm.

Key Features

  • Packaged in 8 pin narrow SOIC.
  • Uses an inexpensive 13.500 MHz external crystal.
  • On-chip VCXO (patented) with pull range of 200ppm (minimum).
  • VCXO tuning voltage of 0 to 3V.
  • 25mA output drive capability at TTL levels.
  • Advanced, low power, sub-micron CMOS process.
  • 5V operating voltage Block Diagram VIN X1 13.5 MHz pullable crystal X2 Voltage Controlled Crystal Oscillator PLL/Clock Synthesis Circuitry Output Buffer 27MHz MDS 2.

MK2727 Low Cost 27 MHz VCXO Description The MK2727 is MicroClock’s lowest cost, low jitter, high performance VCXO and PLL clock synthesizer designed to replace expensive 27MHz VCXOs. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3V input voltage to cause the output clocks to vary by ±100 ppm. Using MicroClock’s patented VCXO and analog PhaseLocked Loop (PLL) techniques, the device uses an inexpensive external 13.5 MHz pullable crystal input to produce a 27 MHz output clock. MicroClock manufactures the largest variety of Set-Top Box and multimedia clock synthesizers for all applications. If more clock outputs are needed, see the MK2731 or MK277x family of parts. Consult MicroClock to eliminate VCXOs, crystals and oscillators from your board.
