- Applicati***:
The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 250 Kbps. The communication range can be increased by enabling a Forward Error Correction option, which is integrated in the modem.
TRW-811S provides extensive ha***are support for packet handling, data buffering, burst tran***issi***, clear channel asses***ent, link quality indication and wake-on-radio.The main operating parameters and the 64-byte tran***it/receive FIFOs of TRW-811S can be controlled via an SPI interface. In a typical system, the TRW-811S will be used together with a microcontroller and a few additional passive components.
- Key Features:
- ***all size
