The device has four banks 1414 P4P4 55 CLCLKK44 of outputs with each bank supporting two CMOS outputs at the same frequency. Using Skyworks Solutions patented MultiSynth fractional divider technology, all 66 1313 P5P5 CLCLKK55 717188 99 1010 111122 outputs are guaranteed to have 0 ppm frequency synthesis error regardless of configuration, enabling the replacement of multiple clock ICs and crystal oscilla- tors with a single device.
