MC12080 Datasheet, PDF (1/4 Pages) ON Semiconductor – 1.1 GHz Prescaler High Frequency Input Signal

MC12080
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. An
820 Ω resistor is recommended to achieve a 1.2 V_pp 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 V_out specification for various divide
ratios at 1.1 GHz input frequency.
