ANALOG CHARACTERISTICS (CS4340-DSZ) (Continued)
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: 4. 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.
5. De-emphasis is only available in Single-Speed Mode.
