MC12026ADR2G

1.1GHz双模预分频器

The MC12026 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.
