IT66121FN: Low Power Transmitter with HDMI1.4 3D Embedded CEC
این آیسی یک فرستنده HDMI می باشد که با گرفتن داده های RGB و سیگنال های کلاک و همزمان کننده عمودی و افقی، آن را به استاندارد HDMI جهت انتقال تبدیل میکند.
The IT66121 is a high-performance and low-power single channel HDMI transmitter, fully compliant with HDMI 1.3a, HDCP 1.2 and backward compatible to DVI 1.0 specifications. IT66121 also provide the HDMI1.4 3D feature, which enables direct 3D displays through an HDMI link. The IT66121 serves to provide the most cost-effective HDMI solution for DTV-ready consumer electronics such as set-top boxes, DVD players and A/V receivers, as well as DTV-enriched PC products such as notebooks and desktops, without compromising the performance. Its backward compatibility to DVI standard allows connectivity to myriad video displays such as LCD and CRT monitors, in addition to the ever-so-flourishing Flat Panel TVs.
Aside from the various video output formats supported, the IT66121 also supports 8 channels of I2S digital audio, with sampling rate up to 192kHz and sample size up to 24 bits. IT66121 also support S/PDIF input of up to 192kHz sampling rate.
The newly supported High-Bit Rate (HBR) audio by HDMI Specifications v1.3 is provided by the IT66121 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
By default the IT66121 comes with integrated HDCP ROMs which are pre-programmed with HDCP keys that ensures secure digital content transmission. Users need not worry about the procurement and maintenance of the HDCP keys.
The IT66121 also provides a complete solution of Consumer Electronics Control (CEC) function. This optional CEC feature of HDMI specification allows the user to control two or more CEC-enabled devices through HDMI network. With IT66121 embedded CEC PHY, user can use high-level software API to easily implement all the necessary remote control commands. The CEC bus related protocol is handled by the CEC PHY which eliminates extra loading of the MCU.
