RTL8211E-VB-CG datasheet


Description :

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.


1. Built-in Wake-on-LAN (WOL)
2. Supports Interrupt function
3. Supports Parallel Detection
4. Crossover Detection & Auto-Correction
5. Automatic polarity correction
6. Supports PHYRSTB core power Turn-Off
7. Baseline Wander Correction

SP3490EN Datasheet PDF – Full Duplex RS-485 Transceiver

Part Number : SP3490EN

Function : +3.3V Low Power Full Duplex RS-485 Transceivers with 10Mbps Data Rate

Package : SOP 8 Pin Type

Manufacturers : Signal Processing Technologies

Pinouts :

SP3490EN datasheet


Description :

The SP3490 and the SP3491 are +3.3V low power full duplex transceivers that meet the specifications of the RS-485 and RS-422 serial protocols. These devices are pin-to-pin compatible with the Sipex SP490 and SP491 devices as well as popular industry standards. The SP3490 and the SP3491 feature Sipex’s BiCMOS process, allowing low power operation without sacrificing performance.


1. Full Duplex RS-485 and RS-422 Transceivers
2. Operates from a single +3.3V supply
3. Interoperable with +5.0V logic
4. Allows up to 32 transceivers on the serial bus

Pinout :

Pin 1 – VCC – Positive supply +3.00 < VCC < +3.60
Pin 2 – R – Receiver output.
Pin 3 – D – Driver input.
Pin 4 – GND – Ground connection.
Pin 5 – Y – Non-inverting driver output.
Pin 6 – Z – Inverting driver output.
Pin 7 – B – Inverting receiver input.
Pin 8 – A – Non-inverting receiver input.
