• A receive clock from the HSC or OmniVision connector (
• A local 27 MHz oscillator
• An external clock source using SMA connector (not populated) and
a clock shaping circuit
The clock is not necessarily a 27MHz clock. For example, ADCs
and DACs can use any clock source that is compliant with the sam-
pling rate.
