GM60028H DisplayPort transmitter IC

The GM60028H is a DisplayPort transmitter IC designed for the transmission of secure, high-bandwidth, uncompressed digital audio-video content for next-generation TV, projector, and PC display systems. It has a single link DisplayPort output comprising four main lanes and one auxiliary channel. The total available link bandwidth is 10.8 Gbps, which is suitable for transmission of high resolution digital video and audio content. The DisplayPort link bandwidth supported by GM60028H can transmit 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 GM60028H supports RGB and YUV video color formats with a color depth of 12 (YUV 4:2:2 only), 10, and 8 bits. The GM60028H also supports both compressed and uncompressed audio formats. The 60-bit LVTTL input ports on GM60028H can be mapped to receive video data streams either in two pixels per clock or single pixel per clock of chosen color depth. The audio signal is connected through multi-channel I2S or SPDIF ports. The received video signal is mapped onto DisplayPort main link, along with corresponding audio signal. The GM60028H supports HDCP 1.3 content protection scheme (HDCP 1.3) for secure transmission of digital audio-video content.

The GM60028H can be configured by an external Host through the I²C host interface. This device also includes general purpose inputs/outputs that can be used for controlling system components. The GM60028H 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.
