PulseCore Semiconductor ASM3P2855B
ASM3P2855B is a part of the two chip custom clock generator solution for NEC 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. The custom clock generator ASM3P2855B works with a Supply Voltage of 3.3V.| Part No. | ASM3P2855B |
