ASM3P2855D Custom Clock Generator for FAX System Features - - - - - - - Generates Custom Clocks for FAX system from an inexpensive 24MHz Crystal 3 x 50MHz synchronized clocks 5 x 54.8MHz synchronized clocks 1 x 19.52MHz clock for Scanner REFOUT Clock Supply Voltage 3.3 V ± 0.3V Available in 16L TSSOP, Green package .. Product Description ASM3P2855D is a custom clock generator for FAX system. ASM3P2855D realizes all the ten 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 54.8MHz clocks and three synchronized 50MHz PCI clocks that can be used by CPU, HDD, PCI Analyzer, ASIC2 and ASIC3, Ethernet, LAN PHY and for the CPU Timer, a 19.52MHz clock used by ASIC1 for Scanner. The custom clock generator ASM3P2855D works with a Supply Voltage of 3.3V ± 0.3V. The device is available in a 16L TSSOP Green package.
