1 Temperature range: −40°C to +125°C; typical at 25°C.
2 Current consumption specifications are based on mean current values.
3 The demodulator and modulator currents are specified using an external clock. If using an external crystal oscillator, the crystal oscillator current specification must be
added to the corresponding VCC and IOVCC demodulator/modulator current specification to obtain the total supply current required in this mode.
4 The demodulator and modulator currents are specified using an external clock. If using the internal oscillator, the internal oscillator current specification must be
added to the corresponding VCC and IOVCC demodulator/modulator current specification to obtain the total supply current required in this mode.
5 Guaranteed by design and characterization, but not production tested.
6 Specification set assuming a sinusoidal input signal containing preamble characters at the input and an ideal external filter (see Figure 23).
7 If the internal oscillator is not used, frequency accuracy is dependent on the accuracy of the crystal or clock source used.
