Abstract: An optoelectronic system includes a transmit side and a receive side. The transmit side and the receive side each include an oversampled phase locked loop configured to receive a decimated system clock signal. Each phase-locked loop is configured to output a high frequency sampling clock signal that, in the case of the transmit side, may be leveraged to generate an arbitrary current waveform that, in turn, can be delayed by a delay-locked loop before being applied to a current-controlled light emitting element. The receive side can generate a clock signal at the same high frequency as the transmit side and can be configured to trigger a reset of the transmit side so that the high frequency clock signals between the transmit and receive sides are synchronized.
