2.0 GHz Low Voltage Dual
Modulus Prescaler
MC12033A
MC12033B
The MC12033 is a high frequency low voltage dual modulus prescaler
used in phase–locked loop (PLL) applications. A high frequency input signal
up to 2.0 GHz is provided for cordless and cellular communication services
such as DECT, PHS, and PCS. The MC12033 can be operated down to a
minimum supply voltage of 2.7 V required for battery operated portable
systems.
The MC12033A can be used with CMOS synthesizer requiring positive
edges to trigger internal counters such as Motorola’s MC145XXX series in a
PLL to provide tuning signal up to 2.0 GHz in programmable frequency
steps. The MC12033B can be used with CMOS synthesizers requiring
negative edges to trigger internal counters.
A Divide Ratio Control (SW) permits selection of a 32/33 or 64/65 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

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.
