Description GM69010H

1 Description

The GM69010H is a highly integrated, receiver IC that converts DisplayPort (DP), HDMI,
and component video input signals into TTL format targeted for TV, Monitor, and projector
applications. It has an HDMI receiver, a high speed triple ADC, and a DisplayPort receiver.
The DisplayPort receiver decodes and separates the audio-video signal from the encrypted
digital stream. The DP link comprises four main lanes and one auxiliary channel with total
available link bandwidth of 10.8 Gbps. The DP 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, dedicated for link management and host-specific information
exchange, such as EDID, MCCS, and CP.

The HDMI receiver is version 1.3 compliant and supports all HD formats with HDCP 1.3
authentication. The analog interface includes triple 10-bit ADC, PLL, clamp control,
programmable offset gain control, and Instant Auto block optimized for capturing PC
graphics signals. This device also includes analog audio inputs for direct connection with
conventional analog AV sources.

The GM69010H can handle full HD video @60 Hz or PC graphics up to WUXGA resolution
@60 Hz with 10/8-bit pixel depth. The decoded video data is converted to LVTTL form and
sent out on a 30-bit TTL bus with data configured as one pixel per clock or two pixels per
clock (dual data rate). The extracted audio data is transmitted on multi-channel I2S or single
wire SPDIF bus depending on audio type. The video color format conversion (RGB to YUV
and YUV to RGB) and sample structure conversion (4:4:4 to 4:2:2 and 4:2:2 to 4:4:4) offers
flexible interfacing with external video processing devices.
