MECL PLL Components Dual Modulus Prescaler

   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.
