Description: Dual PLL Frequency Synthesizer

Features

* ternal reference, OSCout should be left open. fin1, fin2 Frequency Inputs (Pins 4, 7) Input frequency from an external VCO output. Each rising
* edge signal on fin1 decrements the N counter, and when appropriate, the A counter of PLL 1. Similarly, fin2 decrements the counters of PLL 2. These

Applications

* of any voltage higher than maximum rated voltages to this high
* impedance circuit. For proper operation, it is recommended that Vin and Vout be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD except SW1 and SW2 which may range up to 15 V. Unused inputs must always be tied to an appropriate
