Hi, good afternoon, I am an Electronics Engineer specialized in Embedded Systems and Media electronics, I have previous experience working with high speed protocols, such as HDMI with ARC and eARC, and low-level signaling schemes, such as LVDS and TMDS. I am well aware of the potential issues related to these kind of signals, such as signal integrity and bandwidth, crosstalk, controlled impedance, EMI, etc. Finally, I have expertise using several EDA tools, such as Altium Designer, EagleEDA and KiCAD. I have designed several high layer count, high-speed PCBs In the past, can design the board you need.
Regarding the SII9437CNUC, the document linked is a Brief, do you have its complete datasheet (seems that it is protected with NDA).
Please contact me so we can discuss this further, I can guarantee first-class work, offering unlimited reviews until you are completely satisfied with the final job.
PD: Feel free to ask me about previous designs so you can see what quality you can expect from my work.
Regards,
