Memory Output Clock Jitter Specifications on page 49

Provides more information about the external memory interface clock output jitter specifications.

(61) This specification only covers fractional PLL for low bandwidth. The fVCO for fractional value range 0.05–0.95 must be ≥ 1000 MHz.

(62) The cascaded PLL specification is only applicable with the following conditions:

• Upstream PLL: 0.59 MHz ≤ Upstream PLL BW < 1 MHz

• Downstream PLL: Downstream PLL BW > 2 MHz
