Preliminary Information
68
Electrical characteristics are over recommended operating conditions, unless otherwise stated.
*Notes
1. Both mark and space have the same amplitude.
2. Band limited random noise (200-3400Hz). Present when FSK signal is present. Note that the BT band is 300-3400Hz, the Bellcore
band is 0-4kHz.
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 nominal values and are for design aid only: not guaranteed and not subject to production testing.
*Notes
1. Refer to Figures 17 and 20
a. dBV = decibels above or below a reference voltage of 1Vrms.
b. dBm = decibels above or below a reference power of 1mW into 600 ohms. 0dBm = 0.7746Vrms.
