MK2014A Datasheet Fast Ethernet Clock Source

Manufacturer: Integrated Circuit Systems

Overview: I C R O C LOC K.

General Description

The MK2014A is the ideal way to generate clocks for Fast Ethernet cards or systems.

It provides 20MHz and 25MHz clocks from an inexpensive 14.31818 MHz crystal or clock.

In an 8 pin SOIC, the MK2014A can save component count, board space, and cost over surface mount crystals and oscillators, and increase reliability by eliminating mechanical devices from the board.

Key Features

  • Packaged in 8 pin SOIC.
  • Input crystal or clock frequency of 14.318 MHz.
  • Lowest jitter in the industry reliably clocks sensitive Ethernet devices.
  • Output clock frequencies of 20.00 MHz and 25.00 MHz.
  • Zero ppm synthesis error in the output clocks.
  • Full CMOS outputs with 25mA drive capability at TTL levels.
  • 3.3V or 5V±10% supply voltage.
  • Advanced, low power CMOS process.
  • Insensitive to input clock duty cycle Block D.
