MK2772-01 Overview

Description

The MK2772-01 is a low cost, low jitter, high performance VCXO and clock synthesizer for settop boxes. 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 20 pin SOIC
  • Uses an inexpensive 13.5 MHz crystal
  • On-chip VCXO (patented) with pull range of 200ppm (minimum)
  • Ability to switch input sources “on-the-fly”
  • VCXO tuning voltage of 0 to 3V
  • Zero ppm synthesis error (patented) in all clocks. All exactly track 27MHz VCXO
  • All clocks are frequency locked. All will vary the same amount (in ppm) as the VCXO
  • Selectable Audio clock for 256x, 384x, and 512x
  • 25mA output drive capability at TTL levels
  • Advanced, low power, sub-micron CMOS process
