... The clock of the crystal oscillator can be used for clocking the microcontroller. Atmel’s ATARx9x has the special feature of starting with an integrated RC-oscillator to switch on the T5753 with ENABLE = H, and after assume the clock signal of the transmis- sion IC, so that the message can be sent with crystal accuracy. ...

... C achieve a better tolerance value and to have the possibility to realize the Z using standard valued capacitors. C forms together with the pins of T5753 and the PCB board wires a series resonance 1 st loop that suppresses the 1 harmonic, hence the position of C Normally the best suppression is achieved when C pins ANT1 and ANT2 ...
