NOTES: (1) Pins 6, 7, 18, 19: AD0, AD1, BCK, DATA, LRCK (Schmitt trigger input).

(2) Pin 10: RST (Schmitt trigger input with internal pull-up resistor).

(3) Pins 5, 21: MCKO, SCKO. (4) Pin 16: ZERO (open drain output).

(5) Pins 8, 9: SCL, SDA.

(6) Pin 9: SDA (open drain output, IOL = 3mA).

(7) Pin 9: SDA (from VIHMIN to VILMAX with a bus capacitance from 10pF to 400pF).

(8) Pins 8, 9: SCL, SDA (input current each I/O pin with an input voltage between 0.1VDD and 0.9VDD).

(9) This characteristic is the requirement for crystal oscillator.

(10) Pin 3: XTUN.

(11) The maximum response time when the XTUN is changed.

(12) The maximum delay time from power on to oscillation.

(13) The maximum lock up time when the PLL frequency is changed.

(14) The maximum delay time from power on to lock up.

(15) Dynamic performance specifications are tested with a 20kHz low-pass filter using a Shibasoku distortion analyzer 725

°C with 30kHz LPF, 400Hz

HPF, Average-Mode.

(16) SNR is tested with infinite zero detection circuit disabled.
