2.8 GHz Prescaler
The MC12079 is a single modulus divide by 64, 128, 256 prescaler for low
power frequency division of a 2.8 GHz (typical) high frequency input signal.
Divide ratio control inputs SW1 and SW2 select the required divide ratio of
÷64, ÷128, or ÷256.
An external load resistor is required to terminate the output. A 1.2 k
resistor is recommended to achieve a 1.6 Vpp output swing, when dividing a
1.1 GHz input signal by the minimum divide ratio of 64, assuming a 12 pF
load. Output current can be minimized dependent on conditions such as
output frequency, capacitive load being driven, and output voltage swing
required. Typical values for load resistors are included in the Vout
specification for various divide ratios at 2.8 GHz input frequency.
2.8 GHz Toggle Frequency
Supply Voltage 4.5 to 5.5 V
Low Power 9mA Typical at VCC = 5.0 V
Operating Temperature Range of –40 to 85°C
