MC12026A_16 Datasheet, PDF (1/6 Pages) ON Semiconductor – 1.1GHz Dual Modulus Prescaler

MC12026A
1.1 GHz 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

1. SW: H = V_CC, 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 V_CC, L = GND to 0.8 V.
