MK2771-12 Datasheet Vcxo And Set-top Clock Source

Manufacturer: Integrated Circuit Systems

Overview: I C R O C LOC K.

General Description

The MK2771-12 is a low cost, low jitter, high performance VCXO and clock synthesizer designed for set-top 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.

Using MicroClock’s patented VCXO and analog Phase-Locked Loop (PLL) techniques, the device uses an inexpensive 13.5 MHz crystal input to produce multiple output clocks including a selectable processor clock, selectable UART and audio clocks, a fixed 11.0592 MHz, and two low skew copies of the 27 MHz.

Key Features

  • Packaged in 20 pin SOIC.
  • Pin for pin and functional upgrade to MK2771-02.
  • Uses an inexpensive 13.5 MHz crystal.
  • On-chip patented VCXO with pull range of 200 ppm.
  • VCXO tuning voltage of 0 to 3 V.
  • Processor frequency of 16.67 MHz, 20 MHz, 32 MHz, 40 MHz, or 50 MHz.
  • Zero ppm synthesis error in all clocks (all exactly track 27MHz VCXO) - patented.
  • 25 mA output drive capability at TTL levels.
  • Advanced, low power, sub-mi.
