LVDS
Controller
Like any integrated circuit the controller will need some peripheral components to make it run properly
Crystal
Keep the XTAL as close as possible to the IC. Where applicable connect the XTAL housing to GND. A via fence reduces coupling to the GND plane. An oscillator can be used alternatively.
Load Capacitor
Load capacitors should be low leakage and stable across temperature range (NP0). For the capacitive load (cload) the stray capacitance of the PCB and the IC pins should be considered:
CL = (C1*C2) / (C1+C2) + Cstray
Cstray ≈ 3…6pF
Common Mode Filter
On differential datalines, a CMC filters common mode noise without affecting the useful signal.
Signal Integrity
Special high speed components are used for EMI protection on high speed differential lines to avoid affecting signal integrity.

SMT Ferrites
On single ended datalines you can use a High Speed SMT Ferrite to improve EMC.
DC Filter
The filter for VCC can have rather high impedance because there is no signal to take care of.

Filter Capacitor
Keep DC-Bias and SRF in mind when selecting MLCCs for filtering.
ESD Protection
ESD Protection devices should be put right behind the connector. Avoid layer hops to prevent propagation of the ESD.
Signal Integrity
Special high speed components are used for EMI protection on high speed differential lines to avoid affecting signal integrity.
XTAL Ground
This GND plane should be connected to IC GND and cover all the traces to the XTAL.
LVDS Lines
For these LVDS lines it is important to use impedance controlled micro strips.

HDMI
Qualified and approved according to HDMI 1.4. High data rate: up to 10.2 Gbps. We support different sizes in accordance with HDMI specification. This means HDMI, Mini HDMI and Micro HDMI all available in SMT.
Short Introduction to LVDS
LVDS technology (Low Voltage Differential Signaling) uses differential data transmission with a serial communication protocol. The differential concept has a great advantage over single-ended systems yet it is much more robust against interferences. The interface has a low power consumption and can be transmitted via a twisted pair cable with a very high data rate.
LVDS systems are used in applications such as HD displays, infotainment systems, industrial cameras, and transmission of large amounts of data.
