ATA6285N/ATA6286N [Preliminary]
ASK Mode
Figure 4-4.
The ATA6285N/ATA6286N is activated by ENABLE = High, FSK = High and ASK = Low. After
activation the microcontroller is switched to external clocking. After typically 0.6 ms, the CLK
driver is activated automatically (the microcontroller waits until the XTO and CLK are ready).
After another time period of 250 µs, the PLL is locked and ready to transmit. The output power
can then be modulated by means of pin ASK. After transmission, ASK is switched to Low and
the microcontroller returns back to internal clocking. Then, the ATA6285N/ATA6286N is
switched to power-down mode with ENABLE = Low and FSK = Low.
