GENERALDESCRIPTION
The ST49C101A-XX is a mask programmable mono-
lithic analog phase locked loop device, designed to
replace existing high frequency crystal oscillator with
a low frequency crystal. The high performance
ST49C101A-XX provides low jitter clock output and
operatesupto180MHz.at3.3voltspowersupply.The
ST49C101A-XXsupportspreprogrammedmultiplica-
tion factors of 2,3,4,5,6,8,10 and 12X.
