1.1 GHz Prescaler
The MC12080 is a single modulus divide by 10, 20, 40, 80 prescaler for
low power frequency division of a 1.1 GHz high frequency input signal.
Divide ratio control inputs SW1, SW2 and SW3 select the required divide
ratio of ÷10, ÷20, ÷40, or ÷80.
An external load resistor is required to terminate the output. A 820 Ω
resistor is recommended to achieve a 1.2 Vpp output swing, when dividing a
1.1 GHz input signal by the minimum divide by ratio of 10, assuming a 8.0 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 1.1 GHz input frequency.
• 1.1 GHz Toggle Frequency
• Supply Voltage 4.5 to 5.5 V
• Low Power 3.7mA Typical at VCC = 5.0 V
• Operating Temperature Range of –40 to 85°C
