BLE radio integration meets analog: integration challenges of tomorrow’s BLE SoC
Fitness trackers, sports watches, toys – consumer appliances, home automation and many other applications benefit from BLE to connect to a smartphone. The DA1469x SoC with BLE 5.x radio provides developers with advanced connectivity features to future-proof their devices and fit the needs of these multiple applications. Next to a powerful digital core, the device packs many analog blocks that need to co-exist next to the RF circuits. For example, haptic drivers, DC/DC conversion, charger and USB can all potentially disrupt BLE radio operation. In this talk, top-down and bottom-up coexistence considerations of high-current analog blocks with BLE RF circuits are discussed, while also presenting system considerations.
