DESCRIPTION
The ABPX1101 is a low-cost general purpose frequency synthesizer and a member of Abracons’ Advanced
Programmable Clock family. Abracon’s ABPX1101 product family offers the versatility of using a single Crystal or
Reference Clock input and producing up to three different system clocks. They can generate any output
frequency up to 200 MHz from fundamental crystal input between 10 MHz - 30 MHz, or a 3rd overtone crystal of
up to 75Mhz, or a Reference clock input of up to 200 MHz. Cascading of the ICs to produce additional clock
frequencies is also supported.
