3.1
Stresses above the values listed below may cause permanent device failure. Exposure to absolute maximum
ratings for extended periods may affect device reliability.
The device is ESD sensitive and should be handled with precaution.
3.2
(*) Divided in two ranges:
The table below gives the electrical specifications of the transmitter under the following conditions:
Supply Voltage = 3.3 V, temperature = 25 ° C, 2-leve l FSK, fc = 915 MHz, Output power = 10 dBm, Bit rate = 38.4
kb/s, f = 100 kHz, XTAL = 16 MHz, modulation by pulling the VCO in open loop (mw2), and conditions as defined
in section 6, unless otherwise specified.
