Description

PLL Mode Setting. These pins set the output frequency of the master clock PLL. See

the Setting Master Clock/PLL Mode section for more details.

1.5 V Common-Mode Reference. A 47 μF decoupling capacitor should be connected

between this pin and ground to reduce crosstalk between the ADCs and DACs. The material of

the capacitors is not critical. This pin can be used to bias external analog circuits, as long as

those circuits are not drawing current from the pin (such as when the CM pin is connected

to the noninverting input of an op amp).

DAC Filter Decoupling Pin. A 10 μF capacitor should be connected between this pin and

ground. The capacitor material is not critical. The voltage on this pin is 1.5 V.

VOUT3 DAC Output. The full-scale output voltage is 0.9 V rms. This output can be used with

an active or passive output reconstruction filter. See the Audio DACs section for details.

VOUT2 DAC Output. The full-scale output voltage is 0.9 V rms. This output can be used with

an active or passive output reconstruction filter. See the Audio DACs section for details.

VOUT1 DAC Output. The full-scale output voltage is 0.9 V rms. This output can be used with

an active or passive output reconstruction filter. See the Audio DACs section for details.

VOUT0 DAC Output. The full-scale output voltage is 0.9 V rms. This output can be used with

an active or passive output reconstruction filter. See the Audio DACs section for details.

ADC Filter Decoupling Pin. A 10 μF capacitor should be connected between this pin and

ground. The capacitor material is not critical. The voltage on this pin is 1.5 V.

1 PWR = power/ground, A_IN = analog input, D_IN = digital input, A_OUT = analog output, D_IO = digital input/output, D_IO/A_IO = digital input/output or analog

input/output.
