ASM3P2855B Datasheet Custom Clock Generator

Manufacturer: PulseCore Semiconductor

Overview: .. August 2007 rev 0.3 Custom Clock Generator for Fax System.

General Description

ASM3P2855B is a part of the two chip custom clock generator solution for NEC FAX system.

Together with ASM3P2854A, ASM3P2855B realizes all the eighteen clocks required by the various ponents and subsystems of the FAX system.

It uses an inexpensive 24MHz crystal as the input to generate five synchronized 50MHz non-spread PCI clocks used by CPU, HDD, PCI Analyzer, ASIC2 and ASIC3, two non-spread synchronized 50MHz clocks for Ethernet and LAN PHY, a 50MHz clock for the CPU Timer, and a 19.52MHz nonspread clock used by ASIC1 for Scanner.

Key Features

  • Generates Custom Clocks for FAX system from an inexpensive 24MHz Crystal 7 x 50MHz synchronized non-Spread Spectrum clocks (for CPU, ASIC2, ASIC3, HDD, and PCI Analyzer, Ethernet, and LAN PHY).
  • 1 x 50MHz for CPU Timer.
  • ASM3P2855B 1x 19.52MHz non-spread clock for Scanner REFOUT Clock Supply Voltage 3.3 V +/- 0.3V Available in 16L TSSOP, Green package Commercial Temperature operation Product.
