Zarlink Semiconductor Inc.
Typical figures are at 25
°
C and are for design aid only: not guaranteed and not subject to production testing
* Test Conditions
1. dBm refers to a reference power of 1 mW delivered into a 600 ohms load.
2. Data sequence consists of all DTMF digits.
3. Tone on = 40 ms, tone off = 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 (0-3 kHz) Gaussian noise.
8. Precise dial tone frequencies are 350 Hz and 440 Hz (
±
2%).
9. Referenced to lowest level frequency component in DTMF signal.
10. Referenced to the minimum valid accept level.
11. Both tones must be within valid input signal range.
12. Internal guard time for ZL490x1 = 20ms.
13. Timing parameters are measured with 70pF load at SD output.
14. Time duration between PWDN pin changes from ‘1‘ to ‘0‘ and ESt/DStD becomes active.
15. Guaranteed by design and characterization. Not subject to production testing.
16. Value measured with an applied tone of 450 Hz.
