Programmable Divide-By-N (LNPDN)

LNPDN block


The LNPDN is a frequency divider module with a customer specified programmable division factor from 2 to 256 for input frequencies up to 700 MHz for the high frequency model and to 200 MHz for the ultra low phase noise model, which includes a noise “clean-up” circuit. The division factor is set by internal jumpers which are factory set to the specified N value. Input and output pads allow easy modification of the levels and an optional output bandpass filter provides a sinewave output for fixed output frequency applications.
