MT88E43
AC Electrical Characteristics
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.
Electrical Characteristics
† 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
3. Production tested at V
† 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.
