NOTES: (1) Sysclk transient is the maximum frequency lock time when the PLL frequency is changed.

(2) Dynamic performance specs are tested with 20kHz low pass filter and THD+N specs are tested with 30kHz LPF, 400Hz HPF, Average-Mode.

(3) SNR is tested at Infinite Zero Detection off.

(4) PLL evaluations tested with 1ns maximum jitter on the 27MHz input clock.
