5 / 30 page CS4228 DS307PP1 5 ANALOG CHARACTERISTICS (Continued) Notes: 5. The passband and stopband edges scale with frequency. For input word rates, Fs, other than 44.1 kHz, the 0.01 dB passband edge is 0.4535×Fs and the stopband edge is 0.5465×Fs. 6. Digital filter characteristics. 7. Measurement bandwidth is 10 Hz to 3 Fs. Specifications are subject to change without notice Base Rate Mode High Rate Mode Parameter Symbol Min Typ Max Min Typ Max Units Analog Output Characteristics - Minimum Attenuation, 10 k Ω, 100 pF load; unless otherwise specified.
