ABPX1130
DESCRIPTION
The ABPX1130 is a low-cost general purpose frequency synthesizer and a member of Abracon’s Advanced Programmable Clock family. Abracon’s ABPX1130 product family can generate any output frequency up to 375 MHz from fundamental crystal input between 10 MHz - 30 MHz, or a 3rd overtone crystal of up to 75Mhz. The ABPX1130 produces differential CMOS outputs to support PECL, LVDS, and CMOS inputs.
