Its 650 MHz -3dB bandwidth ensures the 125 MHz fundamental and its harmonics pass with minimal attenuation, keeping the eye diagram open at the PHY receiver. Each channel presents a maximum 5.5 Ohm on-resistance, which adds about 0.2 dB of insertion loss at 100 MHz into a 100 Ohm differential trace — well within the link budget for a 100-meter Category 5e channel. ## Supply and temperature range for networking gear Operating from a single 3V to 3.6V rail, the switch integrates directly with 3.3V PHY and MAC power domains without a separate regulator. ## Active lifecycle and compliance posture ROHS3 compliance covers the EU RoHS exemption list, so no special handling or documentation is needed for EU-market shipments.","metaTitle":"MAX4890ETJ+T Analog Devices Ethernet Switch, 650MHz","metaDescription":"Active Analog Devices MAX4890ETJ+T Ethernet switch IC, 4-channel SPDT, 650MHz bandwidth, 5.5 Ohm Ron, -40 to 85°C.
