GENERAL DESCRIPTION  
The ST49C107A-04 is a mask programmable monolithic  
analog CMOS device designed to generate two  
simultaneous clocks. The output frequency can vary from  
2 to 130MHz, with up to 16 single selectable  
preprogrammed frequencies stored in internal ROM.  
in order to reduce board space and number of oscillators.  
To provide high speed and low jitter clock, the parts utilize  
a high speed analog CMOS phase locked loop using  
14.318 MHz system clock as the reference clock (note  
that reference clock can be changed to generate optional  
frequencies from a standard programmed device). The  
programmed clock outputs are selectable via four  
address lines.  
The ST49C107A-04 is designed to replace existing CPU  
mother board clocks generated from individual oscillators
