MOTOROLA RF/IF DEVICE DATA
2.8 GHz Prescaler
The MC12089 is a single modulus divide by 64 and 128 prescaler for low
power frequency division of a 2.8 GHz high frequency input signal. The low
power (10.2 mA typical at 5.0 V) and high operating frequency features make
this prescaler ideal in satellite TV receiver applications.
Divide ratio control input SW selects the required divide ratio of
÷64 or
÷128.
On–chip output termination provides 2.5 mA of output current to drive a
12 pF (typical) high impedance load. The output voltage swing under typical
supply voltage and temperature conditions is 1.2 V. If additional drive is
required for the prescaler output, an external resistor can be added in
parallel from the OUT pin to Gnd to increase the output power. Care must be
taken not to exceed the maximum allowable current through the output.
