Figure 4.1 – IR LRM2 Design The Silicon Labs ERF32FG13 SoC is located between the host interface and the RF interface, providing decoupling between host and RF interface. The EFR32FG13 SoC has sufficient buffer space for one telegram. As shown later, telegram processing is defined to minimize delays, so to provide a “transparent-like” behavior.
