MC12080
1.1 GHz Prescaler
Description
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 W 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

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
NOTE: ESD data available upon request.
