MC12026A

1.1GHz Dual Modulus

Prescaler

Description

The MC12026A is a high frequency, low voltage dual modulus

prescaler used in phase-locked loop (PLL) applications.

The MC12026A can be used with CMOS synthesizers requiring

positive edges to trigger internal counters in a PLL to provide tuning

signals up to 1.1 GHz in programmable frequency steps.

A Divide Ratio Control (SW) permits selection of an 8/9 or 16/17

divide ratio as desired.

The Modulus Control (MC) selects the proper divide number after

SW has been biased to select the desired divide ratio.
