1. At 25 C, not including any current drawn from the FX602 pins by external circuitry other
X1, C1 and C2.
2. RD, MODE, RXCK inputs at V
3. All conditions must be met to ensure detection.
4. For V
5. Flat noise in 300-3400Hz band for V23, 200 - 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.
as section 1.4. The internal threshold levels are proportional to V
voltages or different signal level ranges the voltage gain of the input signal amplifier should be
adjusted by selecting the appropriate external components as described in section 1.5
