HD3SS3412A: no using AC coupling

Bonnie Chen

Part Number: HD3SS3412A

Hi team,

my customer using 4:8 switch HD3SS3412A in below condition.

The Wi-Fi PHY rates equate to 5950 Mbps, 4800 Mbps for 5 GHz and 1150 Mbps for 2.4 GHz

however, their IC IQ pair showed: "should be direct connect. not using AC coupling"

can HD3SS3412A direct coupling?or any recommend?

Hi Bonnie,

I recommend to direct connect the HD3SS3412A when the input signal meets the following characteristics.

Amplitude: 0.0V (min) - 1.8Vpp (max)

Common mode voltage: 0.0V (min) - 2.0V (max)

Regards,

Lee

Hi Bonnie,

I would refer directly to the datasheet. This is the strongest guarantee we can make.
