It • 2:1 and 1:2 Switching Supporting Data Rates up will also switch one source to one of two sinks. For to 8.1 Gbps DisplayPort Applications, the HD3SS214 supports • Supports HPD, AUX and DDC Switching switching of the Auxiliary (AUX), Display Data • Wide Differential BW of 8 GHz Channel (DDC) and Hot Plug Detect (HPD) signals in the ZQE package. • Excellent Dynamic Electrical Characteristics • V Operating Range 3.3 V ±10% One typical application would be a mother board that DD includes two GPUs that need to drive one DisplayPort • Extended Industrial Temperature Range of sink. The GPU is selected by the Dx_SEL pin. -40°C to 105°C Another application is when one source needs to • 5 mm x 5 mm, 50-Ball ųBGA Package switch between one of two sinks, example would be a • Output Enable (OE) Pin Disables Switch to Save side connector and a docking station connector. The Power switching is controlled using the Dx_SEL and AUX_SEL pins. The HD3SS214 operates from a • Power Consumption single supply voltage of 3.3 V over extended – Active < 2 mW Typical industrial temperature range -40°C to 105°C. – Standby < 10 µW Typical (When OE = L) Device Information(1) 2 Applications PART NUMBER PACKAGE BODY SIZE (NOM) HD3SS214 • Notebook PCs µBGA (50) 5.00 mm x 5.00 mm HD3SS214I • Desktops/All-in-Ones (1) For all available packages, see the orderable addendum at • Docking Station the end of the data sheet. • Digital Television Simplified Schematic 5Ax(p) 4 5Cx(p) 5Ax(n) 4 4 5Cx(n) 4 Source A AUXAx 2 55CA 2 55CC DP Sink It5A 2 AUXCx 2 AUXBx It5C 2 55C. 2 It5. hE Source B 5x_SEL Control 5.x(p) AUX_SEL 4 5.x(n) 4 I53SS214 2:1 Copyright © 2016, Texas Instruments Incorporated 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
