1.1 GHz Low-Voltage
Dual Modulus Prescaler
The MC12022LVA can be used with CMOS synthesizers requiring
positive edges to trigger internal counters such as Motorola’s MC145XXX
series in a PLL to provide tuning signals up to 1.1 GHz in programmable
frequency steps.
The MC12022LVB can be used with CMOS synthesizers requiring
negative edges to trigger internal counters.
A Divide Ratio Control (SW) permits selection of a 64/65 or 128/129 divide
ratio as desired.
The Modulus Control (MC) selects the proper divide number after SW has
been biased to select the desired divide ratio.
NOTE: The “B” Version Is Not Recommended for New Designs
• 1.1 GHz Toggle Frequency
• Supply Voltage of 2.7 to 5.0 V
• Low–Power 4.0 mA Typical at VCC = 2.7 V
• Operating Temperature Range of –40 to 85°C
• Short Setup Time (tset) 16ns Maximum @ 1.1 GHz
• Modulus Control Input Level Is Compatible With Standard CMOS
and TTL

NOTES: 1. SW: H = VCC, L = Open. A logic L can also be applied by grouunding this pin,
but this is not recommended due to increased power soncumption.
2. MC: H = 2.0 V to VCC, L = GND to 0.8 V.
