NCN7201
2:1 Gigabit Ethernet LAN
Switch with Power-down
Feature
The NCN7201 is an 8−channel, bidirectional Ethernet switch
featuring a power shutdown feature with minimal current
consumption. The NCN7201 is an upgraded version of the NCN7200,
offering improved performance on the data lines while still
maintaining backwards compatibility. This switch is compatible with
10/100/1000 Base−T Ethernet standards, providing high bandwidth
and low return loss. Three additional lines are provided for status
indicator LEDs that switch. ESD protection is built into the switch.
This device can be used to route signals between a single Ethernet
transceiver and an RJ45 connector and a docking station. The
NCN7201 comes in a 42−pin WQFN package (3.5 mm x 9 mm, 0.5
mm pitch).

Description
Power Supply Pin. It is recommended that a bypass capacitor of at least 0.1mF is
placed as close as possible to each VDD pin.
Power Down Pin. When PD is logic high, the device enters Power Down mode.
All switch paths are high impedance. There is no internal pull−up or pull−down
resistor; therefore, this pin cannot be floated.
Channel Select Pin. When PD is logic low, the SEL pin controls whether the AX
pins are connected to BX or CX. There is no internal pull−up or pull−down resist-
or; therefore, this pin cannot be floated.
Data Port A. This is the common side of the data switch.
Data Port B. This is a switchable port of the data switch.
Data Port C. This is a switchable port of the data switch.
LED Port A. This is the common side of the LED switch.
LED Port B. This is a switchable port of the LED switch.
LED Port C. This is a switchable port of the LED switch.
Ground Supply. The exposed pad provides ground reference to the device.
