Chirp spread spectrum modem
Maturity plannedTargets FPGA + ASICDifficulty MediumPriority 2
Chirp spread spectrum modulator and dechirp-FFT demodulator with configurable spreading factor and bandwidth for long-range low-power links.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| iq_in | in | AXI4-Stream | 32 | |
| iq_out | out | AXI4-Stream | 32 |
Standards
- IEEE 802.15.4
Notes
Generic CSS; IEEE 802.15.4 defines a CSS PHY. Proprietary LoRa compatibility requires separate review.
