GENERAL DESCRIPTION

The SGM7301 is a differential 4-channel high-speed

switch. The product can switch dual differential signals

to 1 of 2 locations. With a special design technique

used, it 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

interface.

The SGM7301 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.

No external 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 SGM7301 is available in a Green ULGA-3.5×9-42L

package.
