2.8 GHz Prescaler

MECL PLL Components

÷64/128/256 Prescaler

Legacy Device: Motorola MC12079

The ML12079 is a single modulus divide by 64, 128, 256 prescaler

for low power frequency division of a 2.8 GHz (typical) high frequen-

cy input signal. Divide ratio control inputs SW1 and SW2 select the

required divide ratio of ÷64, ÷128, or ÷256.

An external load resistor is required to terminate the output. A 1.2

kΩ resistor is recommended to achieve a 1.6 V output swing, when

dividing a 1.1 GHz input signal by the minimum divide ratio of 64,

assuming a 12 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

SO 8 = -5P
