Serial to Parallel (Internal Clock)

Serial to Parallel (Internal Clock)

Communication Protocols Application

Deserialization ICs are used so that data can be sent across one wire and interpreted as multiple bits of data. When adding an external clock isn’t realistic, the GreenPAK can use an internal oscillator triggered from an action on the input line, such as a LOW signal that’s held for a pre-determined period.

Design Steps

  1. Configure the shift register as shown in Technique: Building a Shift Register
  2. Add an Input connection for the reset function and connect it to the nRESET of the shift registers.
  3. Configure a preset number of pulses to match the number of shift registers. This is outlined in Technique: Sending a Preset Number of Pulses.
