Layout Considerations
•
Keep the clock and data transmission lines as short as possible with controlled 50
Ω
single-ended
impedance with matched lengths for any TMDS signals connected to RJ45 jack.
•
Use differentially coupled traces with 100
Ω
impedance for DS22EV5110 TMDS outputs.
•
Avoid using vias on the data transmission lines on the input side of the DS22EV5110.
•
Place power supply decoupling capacitors close to the VCC pins.
