Claim:
1. An apparatus comprising: a photonic oscillator circuit configured to generate optical signals, wherein the optical signals are separated by a uniform delay; radio frequency (RF) generating circuitry configured to receive the optical signals and produce a series of reference clock signals having a same clock signal frequency, wherein each reference clock signal in the series includes a uniform delay from a previous clock signal in the series; and a plurality of analog-to-digital converter (ADC) circuits, wherein an ADC circuit includes a signal input to directly receive an RF input signal that is continuous in time and amplitude, and a clock input to receive a reference clock signal of the repeating series of reference clock signals, and wherein the ADC circuits are configured to sample a same RF input signal at the frequency of the reference clock signal with the uniform delay to sample interleaved digital values representing the RF signal.
