Data Sheet
Data Rate
- Can be specified in the discrete data rate register, or specified as a 16-bit word for a user defined data rate. (See
Section 7.1.3)
ter must be configured. (See section 6.4.1)
M deviation must be set for FM operation. (See section 6.4.1.5 and 6.4.1.6)
Preamble
- Set a reasonable length of preamble to insure that the receiver can detect the signal.
