8.3 Feature Description

8.3.1 High Speed Switching

The HD3SS214 supports switching of 8.1 Gbps data rates. The high speed mux is designed with a wide –3dB

differential bandwidth of 8 GHz and industry leading dynamic characteristics. All of these attributes help maintain

signal integrity in the application. Each high speed port incorporates 20-k

Ω pull down resistors that are switched

in when the port is not selected and switched out when the port is selected. Additionally, high speed differential

pairs at port C have internal 20-k

Ω resistor between positive and negative pins
