IT6263: Single Chip De-SSC LVDS to HDMI Converter
The IT6263 is a high-performance single-chip De-SSC LVDS to HDMI converter. Combined with LVDS receiver and HDMI 1.4a Transmitter, the IT6263 supports LVDS input and HDMI 1.4 output by conversion function. The built-in LVDS receiver can support single-link and dual-link LVDS inputs, and the built-in HDMI transmitter is fully compliant with HDMI 1.4a/3D, HDCP 1.2 and backward compatible with DVI 1.0 specification. With high speed LVDS RX, the IT6263 can support resolution up to 1080P and UXGA and 10-bit deep colors. The IT6263 also supports all the HDMI 1.4a 3D mandatory formats which are compliant with HDMI 1.4a 3D Specification.
In order to reduce the EMI noise on legacy system application, the traditional LVDS source will transmit differential signals with spread spectrum, but this spread spectrum is not allowed for HDMI protocol. The IT6263 also builds in unique De-SSC ( De-Spread Spectrum ) function, which can help customers easily adopt the IT6263 on the EMI-concerned platform, with SSC generated from LVDS source processors beforehand.
The IT6263 also encodes and transmits up to 8 channels of I2S digital audio, with sampling rate up to 192 kHz and sample size up to 24 bits. In addition, an S/PDIF input port takes in compressed audio of up to 192 kHz frame rate.
The newly supported High-Bit Rate (HBR) audio by HDMI Specifications v1.3 is provided by the IT6263 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 768 kHz.
Each IT6263 chip comes preprogrammed with an unique HDCP key, in compliance with the HDCP 1.2 standard so as to provide secure transmission of high-definition content. Users of the IT6263 need not purchase any HDCP keys or ROMs.
The single chip IT6263 provides high-performance, cost-effective, LVDS2 HDMI conversion function, and it can be applied to IP TV STBs and Scaler Boxs which need small size video outputs.
