Operating Characteristics Notes:
1. At 25°C, not including any current drawn from the MX602 pins by external circuitry other than X1, C1 and C2.
2. RD, MODE, RXCLK inputs at V , ZP input at V . See Figure 28
SS
DD
3. All conditions must be met to ensure detection.
4. For V = 5.0V with equal level tones and with the input signal amplifier external components as section 3. The
DD
internal threshold levels are proportional to V . For other supply voltages or different signal level ranges the voltage
DD
gain of the input signal amplifier should be adjusted by selecting the appropriate external components as described in
section 4.2
5. Noise (either impulsive or random type that has a flat frequency spectrum at the frequency range of interest) in the
300Hz-3400Hz band for V23 and 200Hz-3200Hz for Bell202.
6. Meeting any of these conditions will ensure non-detection.
7. Open loop, small signal, low frequency measurements.
8. Timing for an external input to the CLOCK/XTAL pin.
