Maximum interdigit pause reject t DO 20 - - ms Propagation delay (St to Q) t PQ - 6 11 µs OE = VDD Propagation delay (St to StD) t PStD - 9 16 µs Output data setup (Q to StD) t QStD - 4.0 - µs Propagation delay (OE to Q), enable t PTE -50 60 ns R L = 10 kΩ, CL = 50 pF Propagation delay (OE to Q), disable t PTD - 300 - ns Crystal clock frequency f CLK 3.5759 3.5795 3.5831 MHz - Clock output (OSC2), capacitive load C LO -- 30 pF - All voltages referenced to V SS unless otherwise noted. For typical values VDD = 5.0 V, VSS = 0 V, TA = 25°C, fCLK = 3.579545 MHz. *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 Ω load. 2. Digit sequence consists of all 16 DTMF tones. 3. Tone duration = 40 ms. Tone pause = 40 ms. 4. Nominal DTMF frequencies are used, measured at GS. 5. Both tones in the composite signal have an equal amplitude. 6. Bandwidth limited (0 to 3 kHz) Gaussian noise. 7. The precise dial tone frequencies are (350 and 440 Hz) ± 2%. 8. For an error rate of better than 1 in 10,000. 9. Referenced to lowest level frequency component in DTMF signal. 10. Minimum signal acceptance level is measured with specified maximum frequency deviation. 11. Input pins defined as IN+, IN-, and OE. 12. External voltage source used to bias V REF. 13. This parameter also applies to a third tone injected onto the power supply. 14. Referenced to Single - Ended Input Configuration on page 3. Input DTMF tone level at -28 dBm. |
