How To Control Impedance In HDMI PCB?

It maintains a controlled impedance during its signal transmission. That’s why it can send quality signals to the receiver with proper bandwidth, resolution, and speed. But, do you know how to ensure impedance control in this PCB?

Impedance mainly depends on some factors which are highly influential in PCB designing. If you take care of the following factors, you can minimize impedance variation during signal transmission.

Dielectric Constant

The dielectric constant refers to the ratio of the electric permittivity of the PCB material in a certain medium and free space. Low DK value is suitable for impedance control in the high-frequency signal transmission lines.

Dielectric Thickness

It indicates the insulating material’s thickness between the PCB trace. Impedance and dielectric thickness have a logarithmic relation. That means if you intend to decrease impedance, you need to use considerably low dielectric thickness.

Copper Thickness

It has a reciprocal relationship with impedance. So, you have to apply proper copper thickness to achieve desired impedance in the PCB transmission line.

Trace Width

Its rule is similar to copper thickness. A wider trace width reduces impedance in HDMI PCB.

HDMI PCB Impedance Control

What Are The Main Difference Between HDMI 1.4 And HDMI 2.0?

HDMI 1.4 and HDMI 2.0 both are effective cables used in connecting printed circuit boards. But, there are some distinguishing factors between these two types of HDMI. Such as:

Frame Rates

HDMI 1.4 is supportive of 4K video frame rates up to 30p. On the contrary, HDMI 2.0 deals with the same video frame rates up to 60p.

Bandwidth

Besides, HDMI 2.0 offers better bandwidth in displaying video content. It is capable of transporting 4K videos at 10-12 bit color depths. But, HDMI 1.4 ensures around 8-bit color depth during transmitting 4K video content.

Video Streaming

You can enjoy dual video streaming at the same time with HDMI 2.0 PCB cables. It is compatible with 18 Gbps speed that allows double 1080p streaming with premium audio. It makes HDMI 2.0 more worthwhile than HDMI 1.4.

Functionality

Both HDMI 1.4 and HDMI 2.0 are highly functional in controlling multiple devices. But, HDMI 2.0 develops the picture quality and visual range of digital signals. Again, it ensures outstanding audio quality during signal transmission.

HDMI 1.4 can’t provide high-quality performance always like HDMI 2.0 while handling multiple devices. That’s why the applications of HDMI 2.0 in high-density PCB projects are increasing.

How To Stack Layers In HDMI PCB Design?

HDMI PCB improves the quality of high-speed signal transmission in electronics devices. Its layer stacking is unique from traditional circuit board designs. You need to consider some factors while designing the PCB layers.

• The multilayer PCB stackup should contain a minimum of 4 layers. It is effective for EMI reduction.
• Place TMDS (Transition-minimized Differential Signaling) signal layer at the top position. It reduces the use of Vias. So, you can apply a minimum number of PCB vias to ensure a clear signal path from HDMI to the receiver circuit.
• Next to the TMDS signal layer, place the ground plane. This is effective for achieving a controlled impedance. Besides, it creates a smooth return path for the current.
• Stack the power plane next to the ground plane. This placement rates the bypass capacitance that significantly reduces EMI in high-speed signal transmission systems.
• Route the slow control layers at the bottom. This stacking of the bottom layer improves the flexibility in transferring high-speed signals.
• Place ground and power planes as close as possible to each other.

Why Do You Need To Use Decoupling Capacitors In HDMI PCB?

Sometimes, HDMI PCB requires a significant amount of supply current in response to the internal switching. Then, the decoupling capacitor starts functioning. It provides sufficient charge to the integrated circuits.

It prevents the circuit board from transferring signals having low integrity and data errors. That means, the decoupling capacitor ensures signal integrity during high-speed data transmission.

Besides, it functions as an EMC filter in HDMI PCB design. These filters prevent high-frequency RF signals from deteriorating the propagated signals throughout the circuit board.

Connecting a decoupling capacitor in between the ground and power plane leads to creating a series resonant circuit. It affects the impedance stability in the PCB transmission line to a large extent. That’s why you must consider the use of decoupling capacitors while designing a high-speed HDMI PCB.
