GM68020H DisplayPort receiver IC

The GM68020H is a DisplayPort receiver IC designed for the reception of secure, highbandwidth, uncompressed digital audio-video signals for next-generation TV, projector, and PC display systems. It has a single link DisplayPort input comprising four main lanes and one auxiliary channel. The total available link bandwidth is 10.8 Gbps suitable for high resolution digital video content. The DisplayPort link bandwidth in GM68020H can support full HD video (1080p 30-bit color per pixel) @ 120 Hz or support 2560 x 1600 @ 60 Hz graphics along with corresponding audio streams. Unlike conventional display interfaces, DisplayPort link bandwidth can be freely traded between video resolution, refresh rate, and pixel bit depth. The auxiliary channel is a 1 Mbps bidirectional, half-duplex interface dedicated for link and device management.

The GM68020H supports RGB and YUV video color formats with a color depth of 12 (YUV 4:2:2 only), 10, and 8 bits. The GM68020H also supports both compressed and uncompressed audio formats. The 60-bit LVTTL output ports on GM68020H can be mapped to receive video data streams either in two pixels per clock or single pixel per clock of chosen color depth. If the received data comprises audio streams, the extracted audio signal is sent out on the digital audio output bus. This device can support up to 8 channel LPCM audio, or a single wire SPDIF encoded audio. The GM68020H supports HDCP 1.3 content protection scheme for secure reception of digital audio-video content.

The GM68020H can be configured by an external Host through the I²C host interface. This IC also includes general purpose inputs/outputs that can be used for controlling system components.

The GM68020H features color space converter (RGB to YUV, and YUV to RGB) and sample structure converter (4:4:4 to 4:2:2 and 4:2:2 to 4:4:4) for flexible interface with external video processing devices.
