(1) Dynamic performance and dc accuracy are specified at the output of the postamplifier as shown in Figure 32. Analog performance specifications
are measured using the System Two
t Cascade audio measurement system by Audio Precisiont in the averaging mode. For all
sampling-frequency operations, measurement bandwidth is limited with a 20-kHz AES17 filter.
(2) Analog performance in the DSD mode is specified as the DSD modulation index of 100%. This is equilvalent to PCM mode performance at
44.1 kHz and 64 fS.
(3) These parameters are defined at the DSD1793 output pins. Load impedances, R1 and R2, are input resistors of the postamplifier. They are defined
as dc-coupled loads.
