MC12089数据手册恩XP中文资料规格书

描述 Description

Overview The MC12089 is a single modulus divide by 64 and 128 prescaler for low power frequency division of a 2.8GHz high frequency input signal. The low power (10.2mA typical at 5.0V) and high operating frequency features make this prescaler ideal in satellite TV receiver applications.

特性 Features

Divide ratio control input SW selects the
required divide ratio of ÷64 or ÷128.

On-Chip output termination provides 2.5mA of
output current to drive a 12pF (typical) high impedance load.
The output voltage swing under typical supply voltage and
temperature conditions is 1.2V. 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.
•2.8 GHz Toggle Frequency
•Supply Voltage 4.5 to 5.5V
•Low Power Dissipation 51 mW Typical
•Operating Temperature Range of -40 to 85°C
