The ADM2209EARUZ-REEL7 is an integrated circuit (IC) that contains a receiver, transceiver, and driver, components that are essential in many modern interface designs. The device is used in most high performance digital communication systems, such as Gigabit Ethernet, Fibre Channel, SONET, and USB 2.0. Let us take a closer look at the application of this IC, its features and its working principle.

Application Field

The ADM2209EARUZ-REEL7 IC is designed for use in half-duplex systems that rely on transmit/receive switching between two signals, such as gigabit Ethernet. The device is able to support a wide range of media access control (MAC) protocols, such as Carrier Sense Multiple Access / Collision Detection (CSMA/CD), Token Passing, and Demand Priority. The IC supports 10/100/1000 Mbps Ethernet, Fibre Channel and IEEE 802.3ae 10GbE networks. It is also compatible with 5VTTL levels and operates from a single 3.3V supply voltage.

The IC consists of two independent transceiver channels. Each channel supports an independent PHY layer, which allows for fully duplex communication. The IC is capable of driving 10/100/1000 Mbps Ethernet signals and can be used in both uplink and downlink applications. The ADM2209EARUZ-REEL7 is also suitable for use in Fibre Channel applications, as it supports various topologies, such as point-to-point and ring networks. In addition, the device has a low power consumption rate and is RoHS compliant.

Features

The ADM2209EARUZ-REEL7 contains two independent, flexibly programmable transceivers, each consisting of a driver and receiver. The integrated circuit supports communication modes such as half-duplex, full-duplex, single ended, and differential operation. It also contains an independent, full-duplex 10/100/1000 Mbps controllable frequency-locked loop (CFL) for both channels. The CFL can be programmed for various speeds, allowing for an efficient system design.

The driver includes an output impedance of 550Ω, low slew rate of 0.75 V/ns, and a high-impedance output control. It also features a differential line driver with receiver input impedance of 70Ω, and a maximum common-mode output voltages of ±0.7 V. The driver ensures maximum eye diagram width at a transmission rate of 2 Gbps with less than 0.7V peak-to-peak differential output voltage.

The receiver includes a maximum common-mode input voltage of ±0.7V, an input impedance of 25Ω and an output voltage swing of 0.15 to 0.85 V. It also provides a noise margin of more than -1.0V when operated at a transmission rate of 2 Gbps, with a dynamic offset of less than 5mV. The receiver features a low-noise preamplifier design to ensure high line-skew tolerance and a high signal-to-noise ratio.

Working Principle

The ADM2209EARUZ-REEL7 is an integrated circuit (IC) that contains a receiver, transceiver, and driver. It operates in half-duplex and full-duplex modes. In the half-duplex mode, the device uses the transceiver to switch between two signals, such as gigabit Ethernet. The receiver is then used to convert the signal from digital to analog, while the driver sends the signal back through the transceiver. In the full-duplex mode, both the transmitter and receiver are used, allowing for simultaneous transmission of data in both directions.

The driver of the ADM2209EARUZ-REEL7 IC includes an output impedance of 550Ω, low slew rate of 0.75 V/ns, and a high-impedance output control. The receiver includes a maximum common-mode input voltage of ±0.7V, an input impedance of 25Ω and an output voltage swing of 0.15 to 0.85 V. The receiver also provides a noise margin of more than -1.0V when operated at a transmission rate of 2 Gbps, with a dynamic offset of less than 5mV.

The ADM2209EARUZ-REEL7 is designed for use in most high performance digital communication systems, such as Gigabit Ethernet, Fibre Channel, SONET, and USB2.0. It offers a wide range of media access control protocols, a low power consumption rate, and support for both 10/100/1000 Mbps Ethernet, Fibre Channel and IEEE 802.3ae 10GBE networks. The device provides flexibility and reliability for your digital interface design, making it an ideal choice for the most demanding applications.
