meaning of TLV320AIC1106 TEST CONDITIONS

Hi.

Please teach it about a meaning of "PCMI data input to -1dB" which is written on a data sheet of TLV320AIC1106.


It is written down in P.6 of the data sheet, TEST CONDITIONS of the Earphone AMP output power with "PCMI data input to -1dB level", but what does this mean specifically?

For the peak amplitude of PCMI, do you mean that you input PCM data of the amplitude that -1dB is small?

Best regards.
