Global RC Oscillator Controller

Global RC Oscillator Controller
Timing Functions Application

Global RC oscillators are used to synchronize multiple devices. The resistive and capacitive elements can be variable for specific frequencies.
Ingredients
- Any dual rail GreenPAK
- Two resistors
- One capacitor

GreenPAK Diagram
Design Steps
- Configure pins as inputs and outputs of oscillator. Feedback output must be a 1x 3-State Output.
- Configure logic to enable the path between the input and output of the oscillator.
- Connect resistor and capacitor to feedback output node. The other resistor node should be connected to VDD2 and the other capacitor node should be connected to ground.
- Connect the other resistor in between VDD and VDD2.
- Connect the feedback output to the oscillator input.
