Notes
1. A percentage of the applied V (70% or 30%).
DD
2. These inputs are compared internally with the Digital-to-Analogue converter.
3. With a minimum signal input level of 50mVrms at the Tx I/P or 65mVrms at the Rx I/P and an output level of
466mVrms.
4. Levels at the input of the Limiter element, centred about V_BIAS (Note 2).
5. This parameter remains within specification when pre-emphasis is employed.
6. With both Input HPF and LPF in circuit, but without pre-emphasis.
7. With Limiter LPF, but without de-emphasis characteristics.
8. This parameter remains within specification when de-emphasis is employed.
9. The gain variation around the centre frequency (ƒc).
10. See Application Information pages (Suggested Evaluation Tests) for information on gain element settings.
11. Mode: Tx with Compressor “OFF;” or in Rx, signal below limiter thresholds; Output level 466mVrms.
Measured in a 30kHz bandwidth.
12. In the Tx mode with the Input Gain Amp set to ≤ 4.0dB.
