Nano kit uses RTL91191 EC. The datasheet is not available on internet. However, as it is indicated in the Nano’s design guide, Nano module includes the Ethernet Phy and ready for magnetic and connector, however my project requires 6 Ports. Can the Nano Ethernet connection (figure 9) be capacitor coupled to a 4-port BCM53134 switch. The BCM53134 is Low Power Digital to Analog Converter (LDAC) and designed for transformerless capacitor-coupling ?
