MT8870D/MT8870D-1 ISO2-CMOS

4-18

‡ Typical figures are at 25 °C and are for design aid only: not guaranteed and not subject to production testing.

*NOTES

1. dBm= decibels above or below a reference power of 1 mW into a 600 ohm load.

2. Digit sequence consists of all DTMF tones.

3. Tone duration= 40 ms, tone pause= 40 ms.

4. Signal condition consists of nominal DTMF frequencies.

5. Both tones in composite signal have an equal amplitude.

6. Tone pair is deviated by ±1.5 %± 2 Hz.

7. Bandwidth limited (3 kHz ) Gaussian noise.

8. The precise dial tone frequencies are (350 Hz and 440 Hz) ± 2 %.

9. For an error rate of better than 1 in 10,000.

10. Referenced to lowest level frequency component in DTMF signal.

11. Referenced to the minimum valid accept level.

12. Guaranteed by design and characterization.
