AC Electrical Characteristics - Timing Parameter Measurement Voltage Levels
a. dBV = decibels above or below a reference voltage of 1Vrms. Signal level is per tone.
b. dBm = decibels above or below a reference power of 1mW into 600 ohms. 0dBm = 0.7746Vrms. Signal level is per tone.
c. Twist = 20 log (f
H
amplitude / f
L
amplitude).
*Notes:
1. Both tones have the same amplitude.
2. Band limited random noise 300-3400Hz. Measurement valid only when tone is present.
3. Tip/Ring signal level. Input opamp configured to 0dB gain at V
DD
=5V+/-10%, -3.38dB gain at V
DD
=3V+/-10%. (see Figure 10)
AC Electrical Characteristics are over recommended operating conditions, unless otherwise stated.
Typical figures are at 25
