(Relative to 1 kHz)
Combined Digital and On-chip Analog Filter Response - Double Speed Mode - 96 kHz
Passband (Note 9)
Frequency Response 10 Hz to 20 kHz
StopBand
StopBand Attenuation
Group Delay
Passband Group Delay Deviation
Combined Digital and On-chip Analog Filter Response - Quad Speed Mode - 192 kHz

Notes: 9. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 46 to 69) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
10. Single and Double Speed Mode Measurement Bandwidth is from stopband to 3 Fs.
Quad Speed Mode Measurement Bandwidth is from stopband to 1.34 Fs.
11. De-emphasis is available only in Single Speed Mode.
