GL800USB is a high performance USB 2.0 Transceiver compliant with the UTMI (USB 2.0 Transceiver Macrocell Interface) Specification proposed by Intel. The UTMI specification defines a standard interface to USB 2.0 high-speed transceivers that enables common design across prototype and production implementations. The USB 2.0 UTMI Transceiver, which handles the low level USB protocol and signaling, and shifts the clock domain of the data from the USB 2.0 rate to one that is compatible with the general logic.
1. Complies with Universal Serial Bus Specification 2. Complies with USB 2.0 Transceiver Macrocell Interface (UTMI) Specification 3. 16 bit Bi-directional Serial Interface Engine (SIE) bus 4. Data and clock recovery from serial stream on the USB 5. Holding registers to stage transmit and receive data
The Realtek RTL8211E-VB-CG/RTL8211E-VL-CG/RTL8211EG-VB-CG are highly integrated Ethernet transceivers that comply with 10Base-T, 100Base-TX, and 1000Base-T IEEE 802.3 standards. They provide all the necessary physical layer functions to transmit and receive Ethernet packets over CAT.5 UTP cable.
The RTL8211E-VB(VL)/RTL8211EG-VB uses state-of-the-art DSP technology and an Analog Front End (AFE) to enable high-speed data transmission and reception over UTP cable. Functions such as Crossover Detection & Auto-Correction, polarity correction, adaptive equalization, cross-talk cancellation, echo cancellation, timing recovery, and error correction are implemented in the RTL8211E-VB(VL)/RTL8211EG-VB to provide robust transmission and reception capabilities at 10Mbps, 100Mbps, or 1000Mbps.
Data transfer between MAC and PHY is via the Reduced Gigabit Media Independent Interface (RGMII) or Gigabit Media Independent Interface (GMII) for 1000Base-T, 10Base-T, and 100Base-TX. The RTL8211E-VB and RTL8211EG-VB support 3.3V or 2.5V signaling for RGMII/GMII. The RTL8211E-VL supports 1.5/1.8V signaling for RGMII.
