Table 15: AC Timing Specifications, continued
Unless otherwise stated, all power supplies = 3.3V, no load on any output, and ambient temperature TA = 25°C. Parameters denoted with an asterisk ( * ) represent nominal characterization data and
are not currently production tested to any specific limits. MIN and MAX characterization data are ± 3σ f rom typical. Spread spectrum modulation is disabled except for Rise/Fall time measurements.
