1. CHARACTERISTICS AND SPECIFICATIONS

997 Hz; Fs = 48 kHz; XTI = 12.288 MHz (PLL disabled). Measurement Bandwidth is 20 Hz to 20 kHz.)

2. Bench tested only.

3. Filter characteristics scale with output sample rate.

5. Measured using differential analog input circuit, see Figure 10.

6. Filter Response is not tested but guaranteed by design.
