Table 17. Power Consumption by Powerdown Mode for the CS4202

1 Assuming standard resistive load for transformer coupled coaxial S/PDIF output (Rload = 292 Ohm, DVdd

= 3.3 V) (Rload = 415 Ohm, DVdd = 5 V). General: IDVdd S/PDIF = IDVdd + DVdd/Rload/2

2 HP_OUT_L, HP_OUT_R driving 4 Vpp into 32 Ohm resistive load.
