8.1 Overview

The HD3SS215 is a generic analog, differential passive switch that can work for any high speed interface applications, as long as it is biased at a common mode voltage range of 0 V to 3.3 V and has differential signaling with differential amplitude up to 1800 mVpp. It employs adaptive tracking that maintains the high speed channel impedance over the entire common mode voltage range. In high-speed applications and data paths, signal integrity is an important concern. The switch offers excellent dynamic performance such as high isolation, crosstalk immunity, and minimal bit-bit skew. These characteristics allow the device to function seamlessly in the system without compromising signal integrity. The 2:1/1:2, mux/de-mux device operates with ports A or B switched to port C, or port C switched to either port A or B. This flexibility allows an application to select between one of two Sources on ports A and B and send the output to the sink on port C. Similarly, a Source on port C can select between one of two Sink devices on ports A and B to send the data. To comply with DisplayPort, DP++ and HDMI applications, the HD3SS215 also switches AUX, HPD, and DDC along with the high-speed differential signals. The HPD and data signals are both switched through the Dx_SEL pin. AUX and DDC are controlled with AUX_SEL and Dx_SEL. The Functional Modes section contains information on how to set the control pins.

With an OE control pin, the HD3SS215 is operational, with low active current, when this pin is high. When OE is pulled lowed, the device goes into standby mode and draws very little current in order to save power consumption in the application.
