ANALOG CHARACTERISTICS

(Continued)

Notes:

2.

Filter response is not tested but is guaranteed by design.

3.

Response is clock dependent and will scale with Fs. Note that the response plots (

Figures 15

-

22

) have

been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.

4.

For Base-Rate Mode, the Measurement Bandwidth is 0.5465 Fs to 3 Fs.
For High-Rate Mode, the Measurement Bandwidth is 0.577 Fs to 1.4 Fs.

5.

De-emphasis is not available in High-Rate Mode.
