GENERAL DESCRIPTION

The SGM7300B is a differential 2-channel switch which

can be used for both multiplexer (MUX) and demultiplexer

(DEMUX) configurations. The device can be used for PCI

Express Generation 3, USB 3.1 and other high-speed

serial interface applications.

The product can switch dual differential signals to 1 of 2

locations. Using these design techniques, SGMICRO

minimizes the impedance of the switch so that the

attenuation observed through the switch can be ignored

and minimizes the inter-channel skew and inter-channel

crosstalk required for high-speed serial interfaces. The

SGM7300B can achieve extremely low power

consumption by extending existing high-speed ports. In

order to achieve high ESD tolerance, the ESD

protection circuits are integrated into ICs.

SGMICRO optimizes the pins to match the product to

different application layouts. The SGM7300B is suitable

for edge connectors with different signal sources on the

motherboard, with input and output pins on opposite

sides of the package.

No external DC blocking capacitors are required on the

RF paths as long as no external DC voltage is applied,

which can save PCB area and cost.

The SGM7300B is available in a Green TLGA-2.5×4.5

-20L package.
