POE方案如何選擇

Other Parts Discussed in Thread: TPS23750, TPS23753A

產品需要支持802.3af協議,產品中有Line、MIC模擬音頻輸入輸出,也有HDMI,I2S數字音頻的輸入和輸出,baidu搜索有看到一些文章說非隔離的POE方案不適合帶有音頻的方案,會有較大干擾,初次做POE的項目,一頭霧水,希望能給些意見。

方案選擇時,在TI產品中心可以搜索到20多個產品型號,實在不知道哪一種最適合,希望能給些推薦意見

比如TPS23750、TPS23753A、TPS23755TPS23757TPS23785BTPS23754,該如何選擇
