MECL PLL Components

Dual Modulus Prescaler

Legacy Device: Motorola 12509, 12511, 12513

These devices are two–modulus prescalers which will divide by

5 and 6, 8 and 9, respectively. A MECL–to–MTTL translator is

provided to interface directly with the Motorola MC12014

Counter Control Logic. In addition, there is a buffered clock input

and MECL bias voltage source.
