  • Author: Jon Klein
  • Description: Sequentially enable and disable channels with configurable delay
  • GitHub repository
  • Clock: 12500 Hz

How it works

Counters and registers control and track the state of channel activations. The delay input sets the counter threshold.

How to test

After reset, bring enable high to enable channels sequentially, starting with channel 0. Bring enable low to switch off channels sequentially, starting with channel 7.

External hardware

None, but could be useful for GaAs amplifiers or other circuits which need sequenced power supplies.
