THEORY OF OPERATION INTRODUCTION The primary function of the AD8193 is to switch the high speed signals from one of two (HDMI or DVI) single-link sources to one output. Each source group consists of four differential, high speed channels. The ...

AD8193 OUTPUT CHANNELS Each high speed output differential pair is terminated to the 3.3 V VTTO power supply through two single-ended 50 Ω on-chip resistors, as shown in Figure 20. These matched on- chip back-terminations absorb reflections on the output ...

APPLICATION NOTES SWITCHING HIGH SPEED SIGNALS The AD8193 is a quad 2:1 TMDS switch that is used to switch the high speed signals of two input HDMI links to a single HDMI output. SWITCHING LOW SPEED SIGNALS Because the AD8193 ...

AD8193 Both traces of a given differential pair must be equal in length to minimize intrapair skew. Maintaining the physical symmetry of a differential pair is integral to ensuring its signal integrity; excessive intrapair skew can introduce jitter through duty ...

Auxiliary Control Signals There are four single-ended control signals associated with each source or sink in an HDMI/DVI application. These are hot plug detect (HPD), consumer electronics control (CEC), and two display data channel (DDC) lines. The two signals on ...

AD8193 Evaluation Board The AD8193 evaluation board illustrates one way to implement a 2:1 HDMI link switch with an AD8193 and a CMOS switch. The AD8193 evaluation board deviates from a typical applica- tion in that it uses an HDMI ...

Figure 26 shows the layout of the TMDS traces. These are 100 Ω differential, controlled-impedance traces. Serpentine traces are used for some of the paths to match the lengths within a group of four. The gray traces are routed on ...
