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.
Features
• 1.1 GHz Toggle Frequency
• Supply Voltage 4.5 to 5.5 V
• Low Power 4.0 mA Typical
• Operating Temperature Range of −40 to 85°C
• The MC12026 is Pin Compatible with the MC12022
• Short Setup Time (t
set
) 6.0 ns Typical @ 1.1 GHz
• Modulus Control Input Level is Compatible with Standard CMOS
and TTL
• These Devices are Pb-Free, Halogen Free and are RoHS Compliant
