Transfer Characteristics
Set the power and reset connections as described above in "1.1.1. Supply Voltages". Connect a function generator via a serial resistor of 1k5 to pin 4 of connector 1000. Use the
function generator as a sine wave generator with output level of 1Vtt. Check this AC value with an AC

8.3.8Audio Part - DAC
Description
The DAC used, is the UDA1320 bit stream, continuous calibration. I2S signals from various formats can be entered at pins 1,2 and 3. If these signals are in phase with the delivered system clock at pin 6, the DAC will reproduce analog output signals at pins 14 and 16. 0dB level is 0.85Vrms. These analog signals are at 1.65Vdc level.
The DAC has features which can be checked on the input pins. Mute will switch off the analog signals.

I2S
I2S is a kind of digital audio format, consisting out of 3 lines : CLOCK, WORDSELECT and DATA.
WORD-SELECT
Word select (WS) indicates whether the
