8-CHANNEL HIGH DEFINITION AUDIO CODEC
1. With +30 dB Boost on, 1.00 Vrms with Boost off.
2. Ratio of Full Scale signal to noise output with -60dB signal, measured “A weighted” over a 20 Hz to a 20 KHz
3. ± 1dB limits for Line Output & 0 dB gain, at -20dBV
4. Amplitude of THD+N, measured with A-weighting filter, over 20 Hz to 20 KHz bandwidth.
5. Ratio of Full Scale signal to idle channel noise output is measured “A weighted” over a 20 Hz to a 20 KHz
6. Peak-to-Peak Ripple over Passband meets ± 0.25dB limits, 48 KHz Sample Frequency.
7. Stop Band rejection determines filter requirements. Out-of-Band rejection determines audible noise.
8. The integrated Out-of-Band noise generated by the DAC process, during normal PCM audio playback, over a
bandwidth.
bandwidth. (AES17-1991 Idle Channel Noise or EIAJ CP-307 Signal-to-noise Ratio).
bandwidth 28.8 to 100 KHz, with respect to a 1 Vrms DAC output.
