• USB_REFCLK[P, N] - USB 2.0 Controller Reference Clock, Differential, no Spread
Spectrum.
shows the required clock period based on:
• PPM Tolerance = 35 ppm
• Cycle-to-Cycle Jitter = 250 ps
• Spread = 0.00% (no spread spectrum)
• Cycle-to-Cycle Jitter = 250 ps
• Spread = 0.00% (no spread spectrum)
has the AC requirements for these reference clock inputs.
