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 Г 10, Г 20, Г 40, or Г 80.
An external load resistor is required to terminate the output. An
820 W 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. http://onsemi.com
