Descriptions
The IT6613 is a high-performance HDMI transmitter, fully compatible with HDMI 1.3, compatible with HDMI 1.4a 3D and HDCP 1.4 compliance and also backward compatible to DVI 1.0 specifications. The IT6613 supports color depth of up to 36 bits (12 bits/color) and ensures robust transmission 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 DVD/HD-DVD/Bluray players and settop boxes. The IT6613 also supports diverse 3D formats which are compliant with HDMI 1.4a 3D specification.
Aside from the various video output formats supported, the IT6613 also encodes and transmits up to 8 channels of I2S digital audio, with sampling rate up to 192kHz and sample size up to 24 bits. In addition, an S/PDIF input port takes in compressed audio of up to 192kHz frame rate, while Super Audio Compact Disc (SACD) is supported through dedicated DSD ports (Direct Stream Digital ports) at up to 88.2kHz one-bit audio.
The High-Bit Rate (HBR) audio is also provided by the IT6613 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 IT6613 chip 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 IT6613 need not purchase any HDCP keys or ROMs.
The IT6613 is pin compatible with the CAT6613, the previous generation HDMI 1.3 tran

盡管英偉達、AMD 近期發(fā)布了多款 GPU 新品，但是全球芯片短缺的狀況依舊沒有緩解跡象，新發(fā)布的 RTX 3060 顯卡依舊供不應(yīng)求。摩根大通分析師表示，目前 GPU 缺貨的情況可能會持續(xù)到 2022 年。
