Preliminary Rev. 0.5 | 2 F1LS3222 Bluetooth v5.2 Low energy module re connected world. 2. System Overview 2.1 Introduction The F1LS3222 Module combines an energy-friendly MCU with a high performance radio transceiver. The devices are well suited for secure connected IoT multi-protocol devices requiring high performance and low energy consumption. This section gives a short intro-duction to the full radio and MCU system. A block diagram of the F1LS3222 is shown in Figure 3.1 2.2 Radio The F1LS3222 features a highly configurable radio transceiver supporting the Bluetooth Low Energy wireless proto-col. 2.2.1 Antenna Interface The F1LS3222 Module includes an integrated chip –antenna . The table below includes performance specifications for the integrated Chip-antenna. silabs.com | Building a more connected world. Preliminary Rev. 0.5 | 7 F1LS3222 Bluetooth v5.2 Low energy module 2.2.2 Fractional-N Frequency Synthesizer The F1LS3222 contains a high performance, low phase noise, fully integrated fractional-N frequency synthesizer. The synthesizer is used in receive mode to generate the LO frequency for the down-conversion mixer. It is also used in transmit mode to directly generate the modulated RF carrier. The fractional-N architecture provides excellent phase noise performance, frequency resolution better than 100 Hz, and low energy consumption. The synthesizer’s fast frequency settling allows for very short receiver and transmitter wake up times to reduce system energy consumption. 2.2.3 Receiver Architecture The F1LS3222 uses a low-IF receiver architecture, consisting of a Low-Noise Amplifier (LNA) followed by an I/Q down-conversion mixer. The I/Q signals are further filtered and amplified before being sampled by the IF analog-to-digital converter (IFADC). The IF frequency is configurable from 150 kHz to 1371 kHz. The IF can further be configured for high-side or low-side injection, provid-ing flexibility with respect to known interferers at the image frequency. The Automatic Gain Control (AGC) module adjusts the receiver gain to optimize performance and avoid saturation for excellent selec-tivity and blocking performan…
