> +description: |
> + The IT6263 is a high-performance single-chip De-SSC(De-Spread
> +Spectrum) 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.
> +
> + The IT6263 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.
> +
> + The newly supported High-Bit Rate(HBR) audio by HDMI specifications
> + v1.3 is provided by the IT6263 in two interfaces: 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.
