This product is a single-channel interface designed for 10/100/1000M bps Ethernet applications. It is compatible with various 10/100/1000M Base-TX transceivers requiring a 1:1 transmit and receive turns ratio. The device complies with the IEEE 802.3ab standard, including baseline wander compensation. It features a low-profile surface mount packaging suitable for Hi-Temp Reflow Processes (250 peak) and offers enhanced EMC system performance through tuned Common Mode Chokes (CMCs). The operating temperature range is 0 to +70.
