ICS650R-01 - System Peripheral Clock Source

This page provides the datasheet information for the ICS650R-01, a member of the ICS650-01 System Peripheral Clock Source family.

Description

The ICS650-01 is a low cost, low jitter, high performance clock synthesizer for system peripheral applications.

Using analog/digital Phase-Locked Loop (PLL) techniques, the device accepts a parallel resonant 14.31818 MHz crystal input to produce up to eight output clocks.

Features

  • Packaged in 20 pin tiny SSOP (QSOP).
  • Operating VDD of 3.3V or 5V.
  • Less than one ppm synthesis error in all clocks.
  • Inexpensive 14.31818 MHz crystal or clock input.
  • Provides Ethernet and Fast Ethernet clocks.
  • Provides SCSI clocks.
  • Provides PCI clocks.
  • Selectable AC97 audio clock.
  • Selectable USB clock.
  • OE pin tri-states the outputs for testing.
  • Selectable frequencies on three clocks.
  • Duty c.

( DataSheet : www.DataSheet4U.com ) ICS650-01 System Peripheral Clock Source Description The ICS650-01 is a low cost, low jitter, high performance clock synthesizer for system peripheral applications. Using analog/digital Phase-Locked Loop (PLL) techniques, the device accepts a parallel resonant 14.31818 MHz crystal input to produce up to eight output clocks. The device provides clocks for PCI, SCSI, Fast Ethernet, Ethernet, USB, and AC97. The user can select one of three USB frequencies, and also one of three AC97 audio frequencies. The OE pin puts all outputs into a high impedance state for board level testing. All frequencies are generated with less than one ppm error, meeting the demands of SCSI and Ethernet clocking.
