2.0 GHz Low Voltage Dual

Modulus Prescaler

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

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.
