HD3SS212 5.4Gbps DisplayPort 1.2 2-to-1 Differential Switch

1 Features

3 Description

•

Compatible with DisplayPort 1.2 electrical standard

2:1 switching supporting data rates up to 5.4Gbps

Supports HPD switching

Wide -3dB differential BW of over 5.4 GHz

Excellent dynamic characteristics (at 2.7GHz)

– Crosstalk = –50dB

The HD3SS212 is a high-speed passive switch

capable of switching two full DisplayPort 4 lane ports

from one of two sources to one target location in an

application. For DisplayPort applications that

HD3SS212 also supports switching of the Auxiliary

(AUX) and Hot Plug Detect (HPD) signals. HPD path

is a buffer which requires a 125kΩ pull-down resistor

on the HPDC line.

– Isolation = –22dB

– Insertion loss = –1.4dB

A typical application would be a mother board that

includes two GPUs that need to drive one DisplayPort

sink. The GPU is selected by the Dx_SEL pin. The

HD3SS212 is offered in a 48-ball bfBGA package and

specified to operate from a single supply voltage of

3.3V over full industrial temperature range of –40°C to

105°C.

– Return loss = –11 dB

– Max bit-bit skew = 4 ps

VDD operating range 3.3 V ±10%
