ON MC12026AD 1.1 ghz dual modulus prescaler Datasheet

MC12026A
1.1 GHz Dual Modulus
Prescaler
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.

DEVICE MARKING INFORMATION
See general marking information in the device marking
section on page 6 of this data sheet.
1. SW: H = VCC, L = Open. A logic L can also be applied by grounding this pin,
but this is not recommended due to increased power consumption.
2. MC: H = 2.0 V to VCC, L = GND to 0.8 V.
