3 Description

The HD3SS3212 is a high-speed bidirectional

passive switch in mux or demux configurations suited

for USB Type-C™ application supporting USB 3.1

Gen 1 and Gen 2 data rates. Based on control pin

SEL, the device provides switching on differential

channels between Port B or Port C to Port A.

The HD3SS3212 is a generic analog differential

passive switch that can work for any high-speed

interface applications requiring a common mode

voltage range of 0 to 2 V and differential signaling

with differential amplitude up to 1800 mVpp. It

employs adaptive tracking that ensures the channel

remains unchanged for the entire common mode

voltage range.

Excellent dynamic characteristics of the device allow

high-speed switching with minimum attenuation to the

signal eye diagram with very little added jitter. It

consumes <2 mW of power when operational and

has a shutdown mode exercisable by OEn pin
