The 4-bit programmable ECL low-frequency divider is a set of serially connected dividers with the varied dividing ratio 2/3 which is able to scale the structure into maximum dividing ratio increasing. If the dividing ratio is set to 1, the input signal is switched to the output and the circuit is disabled. The differential circuit has high noise immunity.
The block is fabricated AMS BiCMOS 0.35 um technology
