車用聲學爆震感測器介面參考設計
TIDA-00152
概覽
This TIDA-00152 reference design utilizes a dual-channel, signal processing IC for detection of premature detonation in combustion (gasoline) engines. The heart of this design is the TPIC8101 that serves as an interface between acoustical sensors or accelerometers and automobile engine management systems. Programmable features on this device include the selection of engine knock detection sensitivity, engine resonance frequency, and sampling rate control of on-board ADC and DAC in signal processing chain. These features allow the TPIC8101 to be a flexible interface that can adapt to cost and/or processing time constraints of the customer.
特點
- 2 channel device (cars usually have two knock sensors)
- Programmable features (gain, bpf center freq, input freq pre-scalar)
- Broad uC selection (nine selectable external clock frequencies)
- Full SoC (can be used for general analog signal processing)
- Xtal-less solution (providing there is a clock from the MCU)
- AEC-Q100
已開發完全組裝的電路板，僅供測試與性能驗證，且為非賣品。
