ASM3P2855B  
Custom Clock Generator for Fax System  
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  
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 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 components 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 non-  
spread clock used by ASIC1 for Scanner. The custom  
clock generator ASM3P2855B works with a Supply  
Voltage of 3.3V. The device is available in a 16L TSSOP  
Green package and in commercial temperature range.
