The TLSR8258F512 integrates an advanced BLE/802.15.4/2.4GHz RF transceiver. The RF transceiver works in the worldwide 2.4GHz ISM(Industrial Scientific Medical) band.
The transceiver consists of a fully integrated RF synthesizer, a Power Amplifier(PA), a Low Noise Amplifier(LNA), a Tx filter, a Rx filter, a Tx DAC, an ADC, a modulator and a demodulator. The transceiver can be configured to work in the following mode:
All modes support FSK/GFSK/MSK modulations.
The TLSR8258F512 integrates an internal Power Amplifier(PA), which can deliver a maximum 10dBm output power. Besides, This chip supports external PA and LNA by related API
Air interface data rate, the modulated signaling rate for RF transceiver when transmitting and receiving data, is configurable via related API:
For the TLSR8258F512, RF transceiver can operate with frequency ranging from 2.4GHz to 2.4835GHz. The RF channel frequency setting determines the center of the channel.
The baseband is disabled by default. The corresponding API is available for user to power on/down the baseband and enable/disable clock, so that the baseband can be turned on/off flexibly.
The baseband contains dedicated hardware logic to perform fast AGC control, access code correlation, CRC checking, data whitening, encryption/decryption and frequency hopping logic.
The baseband supports all features required by Bluetooth 5 and 802.15.4 specification.
