ICS307-03 - SERIALLY PROGRAMMABLE CLOCK SOURCE

General Description

The ICS307-03 is a dynamic, serially programmable clock source which is flexible and takes up minimal board space.

Output frequencies are programmed via a 3-wire SPI port.

Key Features

  • Crystal or clock reference input.
  • 3.3 V CMOS outputs.
  • Three outputs can be individually configured or shut off.
  • Small 16-pin TSSOP package.
  • Reprogrammable during operation.
  • 3-wire SPI serial interface.
  • Glitch-free output frequency switching.
  • User selectable charge pump current and damping resistor.
  • Power-down control via hardware pin or software control bit.
  • Programming word can be generated by ICS VersaCl.

ICS307-03 SERIALLY PROGRAMMABLE CLOCK SOURCE Description The ICS307-03 is a dynamic, serially programmable clock source which is flexible and takes up minimal board space. Output frequencies are programmed via a 3-wire SPI port. An advanced PLL coupled to an array of configurable output dividers and three outputs allows low-jitter generation of frequencies from 200 Hz to 270 MHz. The device can be reprogrammed during operation, making it ideal for applications where many different frequencies are required, or where the output frequency must be determined at run time. Glitch-free frequency transitions, where the clock period changes slightly over many cycles, are possible. Features • Crystal or clock reference input • 3.
