Power Supply Induced Jitter in High Speed PCB PDN Ripple to VCO or Buffer
In high-speed PCB design, the power delivery network (PDN) is often the unsung hero—or the silent saboteur. Power supply induced jitter is one of the most critical and often misunderstood phenomena, where ripple on the PDN couples into voltage-controlled oscillators (VCOs) or clock buffers, causing timing uncertainty that degrades system margin.
