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
resulting <20 μW.
