DATASHEET

2.4. Chip Specification

The tables below give the electrical specifications of the receiver under the following conditions: Supply voltage VBAT1=

VBAT2=VDD=3.3 V, temperature = 25 °C, FXOSC = 32 MHz, FRF = 915 MHz, 2-level FSK modulation without pre-filtering,

Bit Rate = 4.8 kb/s and terminated in a matched 50 Ohm impedance, unless otherwise specified.

Note

Unless otherwise specified, the performances in the other frequency bands are similar or better.
