Electrical Characteristics - CONT.

Note 1. Exceeding the absolute maximum rating may damage the device.

Note 2. The device is not guaranteed to function outside its operating rating.

Note 3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series

with 100pF.

Note 4. After the release of the STDBY, the device requires an initialization time to settle the REFOSC

and the internal PLL. The first MARK state (ASK HIGH) after exit from STDBY needs to be longer than the

initialization time. The subsequent low to high transitions will be treated as data modulation whereby the

envelope transition time will apply.

Note 5. For the ASK modulation scheme, the part will accept ASK (digital ON/OFF) input and will transmit

the data with a finite extinction ratio and the pin will set the MARK power level.

Note 6. When the MICRF103 is first powered up or it loses power momentarily, it goes into the calibration

mode to tune up the transmit antenna.
