The 8K devices differ in one key area so lets look at the circuit diagram for the Z9G mainboard.Īnd the following components contained on the ONT daughterboard This same mainboard circuit layout is used for pretty much all other MT5893 devices with the exception of their 8K products. Their product diagram perfectly conforms to Sony's own circuit diagram showing the eARC chipset connected to HDMI 3 on the X950G. The eARC chipset in this instance is most likely, but not confirmed, to be the Sil9438 from Lattice Semiconductor. On the diagram you'll see the following components contained on the BM3J19 mainboard

First lets look at the circuit diagram for the X950G mainboard. The MT5893 itself does not support any HDMI 2.1 features so the question must be asked then, how does Sony have TV's based on this SoC which support HDMI 2.1 features such as eARC (the A9F, Z9F, A9G, 850G, X950G, Z9G, A8H, X950H & Z9H), 4K/120 (the Z9G, Z8H & Z9H) and 8K/60 (the Z9G, Z8H & Z9H)? The answer is quite simple, they are using secondary chipsets to implement these features. In December 2016 additional support for HDR Video transport was added to HDMI 2.0b in the recently released CTA-861-G specification, which extends the static metadata signaling to include Hybrid Log-Gamma (HLG). HDMI 2.0b initially supported the same HDR10 standard as HDMI 2.0a as specified in the CTA-861.3 specification. HDMI 2.0a was released on April 8, 2015, and added support for High Dynamic Range (HDR) video with static metadata. 2020 color space, up to 32 audio channels, up to 1536 kHz audio sample frequency, dual video streams to multiple users on the same screen, up to four audio streams, 4:2:0 chroma subsampling, 25 fps 3D formats, support for the 21:9 aspect ratio, dynamic synchronization of video and audio streams, the HE-AAC and DRA audio standards, improved 3D capability, and additional CEC functions. Other features of HDMI 2.0 include support for the Rec. This enables HDMI 2.0 to carry 4K video at 60 Hz with 24 bit/px color depth. HDMI 2.0 uses TMDS encoding for video transmission like previous versions, giving it a maximum video bandwidth of 14.4 Gbit/s. HDMI 2.0 increases the maximum bandwidth to 18.0 Gbit/s. HDMI 2.0, referred to by some manufacturers as HDMI UHD, was released on September 4, 2013. If we look at Wikipedia we see the following info for HDMI 2.0 From Mediatek's own press release the MT5598 is 'a high-performance 1.5GHz quad-core of ARM Cortex processors, with several HDMI 2.0/1.4 interfaces with HDCP 2.2 and USB 3.0 connectivity.' The key here being that it supports HDMI 2.0 and more specifically, because of its support for the HLG HDR format, HDMI 2.0b.

The MT5893 is actually a custom verison of the Mediatek MT5598 ( Archive Link) designed to work in conjunction with Sony's own X1 series of picture processors. There are a variety of TV's based on this chipset. The biggest piece of misinformation seems to be around the ability of the Sony MT5893 SoC to support HDMI 2.1 features. There has been a large amount of misinformation regarding Sony's support of HDMI 2.1 features and what TV's they've released that actually support HDMI 2.1 features or are capable of supporting HDMI 2.1 features.
