Descriptions
The IT6605 is a dual-port HDMI receiver, fully compatible with HDMI 1.3, compatible with HDMI 1.4a 3D and HDCP 1.4 and also backward compatible to DVI 1.0 specifications. The IT6605 with its Deep Color capability (up to 36-bit) ensures robust reception of high-quality uncompressed video content, along with state-of-the-art uncompressed and compressed digital audio content such as DTS-HD and Dolby TrueHD in digital televisions and projectors. The IT6605 also supports diverse 3D formats which are compliant with HDMI 1.4a 3D specification.
Aside from the various video output formats supported, the IT6605 also receives and provides up to 8 channels of I2S digital audio outputs, with sampling rate up to 192kHz and sample size up to 24 bits, facilitating direct connection to industry-standard low-cost audio DACs. Also, an S/PDIF output is provided to support up to compressed audio of 192kHz frame rate. Super Audio Compact Disc (SACD) is supported at up to 8 channels and 88.2kHz through DSD (Direct Stream Digital ports) ports.
The High-Bit Rate (HBR) audio is also provided by the IT6605 in two interfaces: with the four I2S input ports or the S/PDIF input port. With both interfaces the highest possible HBR frame rate is supported at up to 768kHz.
Each IT6605 comes preprogrammed with an unique HDCP key, in compliance with the HDCP 1.4 standard so as to provide secure transmission of high-definition content. Users of the IT6605 need not purchase any HDCP keys or ROMs.
The IT6605 is pin compatible with the CAT6023, the previous HDMI 1.3 r

由于全球各地區(qū)受到新冠病毒的影響逐漸減輕，經(jīng)濟正在恢復，因此 2021 年市場對于芯片的需求還會進一步提升。外媒表示，技嘉、華碩、微星等廠商向東南亞各國輸送的 RTX 3080 顯卡本月不到 20 個集裝箱，今年 2 月向中國大陸運送的 RTX 3080 顯卡預計在100 個集裝箱左右。
臺積電此前決定投資 280 億美元來擴大工廠規(guī)模、提高產(chǎn)能，但建造新工廠需要花費數(shù)月的時間。盡管 GPU 芯片的產(chǎn)能將會提高，但比特幣等數(shù)字貨幣的挖礦需求依舊阻礙了游戲玩家以合理的價格購買顯卡。
