Low-Power Audio CODEC

Semtech Corporation 

XE3005/XE3006

The CODEC bandwidth is around 100 Hz to 10 kHz at the nominal system frequency settings (MCLK = 5 MHz, CKDIV =

1, FSYNC = 20 kHz).

In digital loop back mode, the data entering into the Audio Interface is not transferred to the DAC. However, the

Sandman™ function (if activated) continues to output the SMDA signal based on the data entered into the Audio Interface

(input terminal SDI).

5.1 ABSOLUTE MAXIMUM RATINGS

Stresses above those listed in the following table may cause permanent failure. Exposure to absolute ratings for

extended periods may affect device reliability.

The values are in accordance with the Absolute Maximum Rating System (IEC 134).

All voltages are referenced to ground (VSSA and VSSD).

Analog and digital grounds are equal (VSSA = VSSD).
