Functional description
A, according to port receiver
DisplayPort receiver conforms to the DisplayPort specification version 1.2, by the main link, auxiliary channel (AUX CH) and hot plug detection (HPD) signal,
Main link main link is a one-way, high bandwidth channel, it (HBR2) at 5.4 and 2.7 (gets) and 1.62 (RBR) Gbps rate in 1 or 2 channel, video and audio transmission clock embedded 8 b/10 b encoding serial data,
Table 1, show port is the main link throughput
Auxiliary channel auxiliary channel is 1 Mbps half-duplex two-way channel, used for link management and equipment control, AUX CH is also used for the transmission EDID,
HPD signal is used as an interrupt request to detect its existence
DisplayPort receiver support up to 4096 x2160/30 hz VESA or CEA resolution, color depth up to 30 and downward spread spectrum clock (SSC), through the use of HDCP and DPCP to provide copy protection, 1.3
B, high-definition multimedia interface (HDMI) transmitter
HDMI transmitter conforms to the HDMI 1.4 specification, b is composed of three color channels with a single clock channel, based on TMDS coding, HDMI agreement to allow each color used for the source and receiver equipment transferred between a single RGB color, audio data and secondary data channels, TMDS algorithms based on 8 b/10 b encoding, maximum clock frequency of 297 MHZ, the largest total throughput of 7.128 Gbps clock frequency (2.376 Gbps/channel),
HDMI transmitter support up to 4096 x2160/30 hz VESA or CEA resolution, color depth up to 30 and the sampling rate is 32 kHz, 44.1 kHz and 48 kHz IEC 60985 L - PCM, provide copy protection by encrypting take HDCP is 1.4 and the factory with the key,
C, USB 2.0 full physical interface
AG6311 provide USB 2.0 full speed on the PHY, support through the USB firmware upgrade,
D, universal asynchronous receiver transmitter (UART)
UART interface provides asynchronous communication and full duplex communication mode, the system can through the UART interface upgrade firmware,
E, the integrated circuit (I2C) interface
Inside the integrated circuit (I2C) two-way serial bus interface is 2 line, support the standard (up to 100 kHz) and fast (up to 400 kHz) mode,
AG6311 provide two I2C bus interface, a I2C bus to from mode, used to receive system configuration; An I2C bus to the main mode, display data channel DDC for HDMI connector,
System firmware can through the I2C host (DDC) of HDMI or upgrade the I2C interface from machine,
F, analog-to-digital converter (ADC)
Embed a 10 AD converter, and share as many as two external channel, perform the transformation in scanning mode, the selected a group of analog input to perform automatic conversion, when conversion programming voltage exceeds the threshold, will produce interrupt,
G, video processing unit
Video processing unit performs three functions: color space conversion, gamma control and jitter, executive YUV color space conversion to RGB or RGB to YUV color space conversion, gamma gamma compensation control implementation, jitter noise reduction, video processing to disable these features support the bypass mode, display port receiver output will be directly through the video data processing unit,
