8.10.5 PCM to PCM (Synchronous Sample Rate Converter) Performance
The following specifications are unweighted and apply to all combinations of input and output
rates unless otherwise stated.
Absolute gain accuracy: -0.05dB
All input and output rates except 32kHz:
THD+n (997Hz, -1dBFs): <-130dB (0.000032%)
Dynamic range (997Hz, -60dBFS): >130dB
Frequency response:
-0.05dB: 0Hz…20kHz
-3dB: 0Hz…45% of lowest fs
Input and/or output at 32kHz:
THD+n (997Hz, -1dBFs): <-126dB (0.00005%)
Dynamic range (997Hz, -60dBFS): >128dB
Frequency response:
-0.05dB: 0Hz…14.5kHz
