To calculate the behavior of a transmission system it is important to know the reduction
of the sensitivity due to several influences. The most important are frequency offset due
to crystal oscillator (XTO) and crystal frequency (XTAL) errors, temperature and supply
voltage dependency of the noise figure and IF filter bandwidth of the receiver. Figure 8
shows the typical sensitivity at 433.92 MHz/FSK/20kBaud/ 16 kHz/Manchester versus
the frequency offset between transmitter and receiver with T
+105°C and supply voltage VS1 = VS2 = 2.4 V, 3.0 V and 3.6 V.
