The LogiCORE™ IP Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media Independent Interface (RGMII) design provides the RGMII between RGMII-compliant Ethernet physical media devices (PHY) and the embedded Gigabit Ethernet controller in the Zynq™ 7000 devices. I have used the "rgmii_v2_0_if. RGMII still uses single-ended signaling, but again, offers a 10x increase in data bandwidth for only 3 additional signal lines The receive MAC accepts data via the integrated PHY or via the SGMII/MII/RMII/RGMII interface. Because of this, i would use a Marvell 88e1512 phy (like in the devboard) to do the rgmii->sgmii conversion. Additionally, a second PHY, the KSZ8081 (10/100 Ethernet PHY) is used to provide a second-line interface for simple full-duplex trafic through the KSZ8061. can please someone direct me to any documentation on how to The util_mii_to_rmii IP core is designed to interface the Zynq-7000/Zynq UltraScale+ MPSoC - PS Gigabit Ethernet MAC and Reduced Media Independent Interface (RMII) ADIN1300 PHY from the CN0506 Dual PHY Ethernet evaluation board. Now, that due to obselesence, PHY IC needs to be changed which is compliant with RGMII interface. The LAN7801 is a high performance USB 3. Ensure that the PHY MII interface aligns with the available MII/RGMII/SGMII interface of the Microchip bridge con-troller. SGMII is available only in copper In SGMII-to-RGMII bridge mode, the DP83869 is acting as an RGMII MAC to the connected RGMII PHY (or in your case, another MAC). But I can't seem to establish an ethernet link with this setup. The EVM has connections to use the DP83869 MAC Interface in RGMII and SGMII mode. 10Base-Te, 100Base-TX, 1000Base-T, 100Base-FX and 1000Base-X are supported on the media interface. Therefore, the RMII is optimized for use in high-port density interconnect. TI’s DP83TG720S-Q1 is a 1000BASE-T1 automotive Ethernet PHY with RGMII & SGMII. In Copper mode, the PHY can interface with twisted-pair media through magnetics. rgmii – The MAC is responsible for applying the delay (s) or the delay is included on the PCB directly. No Gigabit Ethernet Switches with RGMII ports could be located. May 31, 2017 · I was reading the SGMII specification and the documentation of a Gigabit MII to SGMII converter (see MAX24287). Tool Support 1. Cache Coherency Translator Intel® FPGA IP 1. 5. MAX24287 1Gps Parallel-to-Serial MII Converter Bidirectional Wire-Speed Ethernet Interface Conversion Can Interface Directly to SFP Modules and SGMII PHY and Switch ICs Serial Interface Configurable as 1000BASE-X or SGMII Revison 1. 25,12. Sep 26, 2024 · Other Parts Discussed in Thread: DP83869 Tool/software: In the DP83896 data sheet, it talks about converting RGMII to SGMII and vice versa but always has a PHY involved: I need to convert from an Ethernet Switch MAC to a CPU MAC like as suggested with a competitor's product VSC8211: Can the DP83869HM support a SGMII to RGMII MAC to MAC connection? Mar 9, 2021 · Why USGMII is better than SGMII/QSGMII: SGMII supports a single 10M/100M/1G network port over 1,25Gbps SERDES between MAC and PHY, while QSGMII supports four 10M/100M/1G network ports over 5Gbps SERDES between MAC and PHY. It decodes the data bytes, strips off the preamble and SFD of each frame. Embedded Software Design Guidelines for Arria 10 Jul 11, 2024 · Part Number: DP83869HM Other Parts Discussed in Thread: DP83869 Tool/software: Hi team, We are using DP83869 PHY in bridge mode in one of our custom board. The PHY is used for RGMII-SGMII conversion. We don't have any MAC interface bridge products right now and SGMII to RMII is a unique request. In principle what I need to do is [MAC] --> GMII link --> [GMII/SGMII bridge IP core] --> SGMII link --> [PHY] so as far I could understand I have to convert the serial input from my Ethernet socket in the VC707 to The gigabit Ethernet PHY support SGMII interface only, and I am looking a proper MAC for it. 1000BASE-SX fiber transceivers conform on the fiber side to the SX standard. Learn more from Cadence. Supported media access control (MAC) interfaces are MII, RGMII and SGMII. The principle objective of RGMII is to reduce the number of pins from 22 to 12 in a cost-effective and technology-independent manner. Altera TSE 1000BASE-X/SGMII PCS core is utilized to convert GMII/MII interface to serial interface through GigE transceiver. zynq will have mdio bus to configure 3 PHY modules, 1 ethernet switch and 1 PCIe switch.
