The transmitter section accepts 32-bit-wide (XGMII) parallel SSTL_2/ HSTL-compatible data, clock and control signals and serializes the 32-bit data into a 4-differential pair of CML high-speed data (XAUI). 23877. How to Implement 10GBASE-R, 10GBASE-R with IEEE 1588v2,. 3 Clause 46 ratified specification enabling a variety of PHY and MAC chips from different vendors to talk the exact same protocol. 3-2005 Clause 46) and I'm really surprised because it mentions a 32b data width for a frequency. PHYs. performance specifications are believed to be reliable but are not verified, and Buyer must conduct and complete all performance and other testing of the products, alone and together with, or installed in, any end-products. This block. 4. RGMII uses four-bit wide transmit and receive datapaths, each with its own source synchronous clock. That being said, there may be an assumption made that a 10 Gb/s MAC/RS/XGMII implementationStatement on Forced Labor. However, per the MII specifications, the MII bus only transfers data at 4 bits (or a nibble) per clock cycle with a 25 MHz clock when operating at a speed of 100 Mbit/s, or 4 bits per clock cycle with a 2.
