The following list lists the SERDES features: * RX Adaptive Decision Feedback Equalizer (DFE) * Programmable continuous time linear equalizer (CTLE) * Rx variable gain control * Rx built-in fault detector (loss-of-lock/loss-of-signal) * Adjustable tx de-emphasis (FFE) * Tx output amplitude control * Supports rx eye monitor * Multiple loopback modes * Prbs generator and checker * Polarity inversion control SERDES6G: The SERDES6G is a high-speed SERDES interface, which can operate at the following data rates: * 100 Mbps (100BASE-FX) * 1.25 Gbps (SGMII/1000BASE-X/1000BASE-KX) * 3.125 Gbps (2.5GBASE-X/2.5GBASE-KX) * 5.15625 Gbps (5GBASE-KR/5G-USXGMII) SERDES10G The SERDES10G is a high-speed SERDES interface, which can operate at the following data rates: * 100 Mbps (100BASE-FX) * 1.25 Gbps (SGMII/1000BASE-X/1000BASE-KX) * 3.125 Gbps (2.5GBASE-X/2.5GBASE-KX) * 5 Gbps (QSGMII/USGMII) * 5.15625 Gbps (5GBASE-KR/5G-USXGMII) * 10 Gbps (10G-USGMII) * 10.3125 Gbps (10GBASE-R/10GBASE-KR/USXGMII) SERDES25G The SERDES25G is a high-speed SERDES interface, which can operate at the following data rates: * 1.25 Gbps (SGMII/1000BASE-X/1000BASE-KX) * 3.125 Gbps (2.5GBASE-X/2.5GBASE-KX) * 5 Gbps (QSGMII/USGMII) * 5.15625 Gbps (5GBASE-KR/5G-USXGMII) * 10 Gbps (10G-USGMII) * 10.3125 Gbps (10GBASE-R/10GBASE-KR/USXGMII) * 25.78125 Gbps (25GBASE-KR/25GBASE-CR/25GBASE-SR/25GBASE-LR/25GBASE-ER) properties: $nodename: pattern: "^serdes@[0-9a-f]+$" compatible: const: microchip,sparx5-serdes reg: minItems: 1 '#phy-cells': const: 1 description: | - The main serdes input port clocks: maxItems: 1 required: - compatible - reg - '#phy-cells' - clocks additionalProperties: false examples: - | serdes: serdes@10808000 { compatible = "microchip,sparx5-serdes"; #phy-cells = <1>; clocks = <&sys_clk>; reg = <0x10808000 0x5d0000>; }; ...
