Application: Reference clock frequency for the Digital Phase locked loop.Technically you can use a ring oscillator circuit in VHDL. What is your application? Are you targeting an FPGA?
Might be possible, but the frequency will be quite unpredictable. Better use external crystal or oscillator and divide from there.Technically you can use a ring oscillator circuit in VHDL. What is your application? Are you targeting an FPGA?
If it's targeting an FPGA, then you have to be really careful since FPGA logic is implemented in lookup tables, which are intrinsically glitchy.Technically you can use a ring oscillator circuit in VHDL. What is your application? Are you targeting an FPGA?
