Describe

Chrontel’s CH7510 is a low-cost, low-power semi-conductor device that integrates a mini-LVDS timing controller (TCON). This device receives high-speed serialized video data and uses the Block Diagram, fully programmable TCON to drive the LCD panel modules through integrated mini-LVDS interface, which is operating in low-voltage and low EMI emission.

The CH7510 is designed to comply with DisplayPort Specification 1.1a and Embedded DisplayPort Specification version 1.2. It supports two Main Link lanes that are capable of receiving data rate running at 1.62Gb/s or 2.7Gb/s. The device can accept input data in 18-bit 6:6:6 or 24-bit 8:8:8 RGB digital formats.

The high performance CH7510’s TCON consists of programmable logic blocks for processing input video data, configurable timing control signals and video data to interface LCD Gate Drivers and Source Drivers. During system power up, setting the power ON/OFF sequence for a particular LCD panel can be achieved through CH7510’s TCON configuration registers. This timing control information is stored in the BOOT ROM along with the EDID information that will be used during the Link Training through AUX Channel.

The CH7510 has a luminance control function to adjust LCD backlight. The brightness control command sent through AUX Channel can be dynamically translated by CH7510 and converted into LCD backlight control signal. The CH7510 will save the last setting of brightness level value in the BOOT ROM and use it upon power up.

Advanced Power Management Unit (PMU) is designed to reduce power consumption in normal operation.
