This block, only usable when in FSK modulation, has five purposes:
Table 2 details some ROMEO2 features versus the bits DME and SOE values.
Table 3 details some ROMEO2 features versus DME values.
Typical crystal frequencies are:
DME
- ID detection,
- Header recognition,
- Clock recovery,
- Output data and recovered clock on SPI port,
- End-of-Message detection.
- 9.864375MHz for 315MHz band,
- 13.580625MHz for 434MHz band.
