COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
The filter characteristics and the X-axis of the response plots have been normalized to the sample rate (Fs) and can
be referenced to the desired sample rate by multiplying the given characteristic by Fs.
Notes: 5. For Single-speed Mode, the measurement bandwidth is 0.5465 Fs to 3 Fs.
For Double-speed Mode, the measurement bandwidth is 0.577 Fs to 1.4 Fs.
6. De-emphasis is only available in Single-speed Mode.
