Edge jitter is a phenomenon where data pulses are stretched or shortened by the radios used to transmit the data or as a result of varying signal strength in the wireless environment. Systems that use PWM schemes must have very wide tolerances on their pulse measurements to allow for edge jitter. Serial transmission schemes sample the data in the center of each bit, so edge jitter has little impact on decoding the data. Another commonly overlooked factor is the legal aspect of the data stream’s duty cycle. The FCC allows the transmitter’s output power to be averaged over 100 ms. Many Amplitude Shift Key transmitters work by turning the transmitter on for a ‘1’ and turning it off for a ‘0’. The result is that a data stream with more ‘0’s will have a lower average output power over that 100 ms time. This allows the output power of the transmitter to be increased and still be legal. The increase in power results in an increase in range and better performance within that range. All Linx encoder and decoders utilize a serial data protocol designed for maximum efficiency, and optimized for a balance of robustness, responsiveness, power, and cost. This allows products based on Linx devices to achieve superior range and immunity from interference and other adverse external influences.
