PWM FILTER CHARACTERISTICS
(Logic “0” = GND = 0 V; Logic “1” = VLS = VLC; VD = 2.5 V; DAI_MCLK = 12.288 MHz; XTAL = 24.576 MHz; PWM
Switch Rate = 384 kHz; Fs = 32 kHz to 192 kHz; Measurement bandwidth is 10 Hz to 20 kHz unless otherwise
specified.)
SWITCHING CHARACTERISTICS - XTI
(VD = 2.5 V, VDP = VLC = VLS = 3.3 V, VDX = 2.5 V to 5.0 V; Inputs: Logic 0 = GND, Logic 1 = VDX)

12. Filter response is not production tested but is characterized and guaranteed by design.
13. XTAL = 49.152 MHz; PWM Switch Rate = 768 kHz; Fs = 96 kHz to 192 kHz.
14. The equation for the group delay through the sample rate converter with OSRATE = 0b is (8.5 / Fsi) + (10
/ Fso) ± (4.5 / Fsi). The equation for the group delay through the sample rate converter with OSRATE = 1b
is (8.5 / Fsi) + (20 / Fso) ± (4.5 / Fsi).
