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 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
