2.0GHz Dual Modulus Prescaler
MC12034A
MC12034B
The MC12034A 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 2.0 GHz in programmable frequency
steps.
The MC12034B can be used with CMOS synthesizers requiring negative
edges to trigger internal counters such as Fujitsu’s MB87001.
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.

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

NOTES: 1. ESD data available upon request.
2. This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this high
impedance circuit. For proper operation, Vin and Vout should be constrained
to the range GND ≤ (Vin or Vout) ≤ VCC.
