Abstract:
A digital video interface receiver adjusts a transfer function of a phase-locked loop circuit having a programmable charge pump, a programmable phase-locked loop filter, or a programmable gain voltage controlled oscillator. The digital video interface receiver monitors and detects errors in a data stream associated with the phase-locked loop circuit. Moreover, the digital video interface receiver changes the transfer function of the phase-locked loop circuit, in response to the detected errors, by changing parameters associated with the programmable charge pump, the programmable phase-locked loop filter, or the programmable gain voltage controlled oscillator of the phase-locked loop circuit so as to change the transfer function of the phase-locked loop circuit.
