Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Modulation is applied to the VCO and therefore the modulation cannot have any DC component. Some kind of coding is needed to ensure that
the modulation is DC free, e.g., Manchester code or block code. With Manchester code the bitrate is half the baudrate, but with 3B4B block
code the bitrate is _ of the baudrate.
Bitrate is the same as the baudrate.
Measured at 19.2k bauds and frequency deviation ± 25kHz (external modulation), jitter of received data: < 45%.
