... The T5753 is activated by ENABLE = H. PA_ENABLE must remain L for typically the CLK signal can be taken to clock the microcontroller and the output power can be modulated by means of Pin PA_ENABLE. After transmission PA_ENABLE is switched to L and the micro- controller switches back to internal clocking. The T5753 is switched back to standby mode with ENABLE = L. 4.2 FSK Transmission The T5753 is activated by ENABLE = H ...

... The clock of the crystal oscillator can be used for clocking the microcontroller. Atmel 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 transmission IC, so that the message can be sent with crystal accuracy. ...

... C ( series); for C erance value and to have the possibility to realize the Z capacitors. C forms together with the pins of T5753 and the PCB board wires a series resonance loop that 1 suppresses the 1 best suppression is achieved when C ANT2. The loop antenna should not exceed a width of 1.5 mm, otherwise the Q-factor of the loop antenna is too high ...
