ATA6286-PNQW 数据手册

With ASK = High the power amplifier is switched on. This is used to perform the ASK modula-

tion. During ASK modulation the IC is enabled with the FSK or the ENABLE pin.

With FSK = Low the switch at pin XTO2 is closed, with FSK = High the switch is open. To

achieve a faster start-up of the crystal oscillator, the FSK pin should be High during start-up of

the XTO because the series resistance of the resonator seen from pin XTO1 is lower if the

switch is off.

The different modes of the ATA6285/ATA6286 are listed in Table 4-1.

ASK Mode

The ATA6285/ATA6286 is activated by ENABLE = open, FSK = High, ASK = Low. The micro-

controller is then switched to external clocking. After typically 0.6 ms, the CLK driver is activated

automatically (i.e., 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 microcon-

troller returns back to internal clocking. Then, the ATA6285/ATA6286 is switched to power-down

mode with FSK = Low.
