Chrontel’s CH7513A is a low-cost, low-power semiconductor

device that translates the Embedded DisplayPort signal to the

LVDS (Low-voltage Differential Signaling). This innovative

DisplayPort receiver with an integrated LVDS transmitter is

specially designed to target the All-In-One PC and the notebook

market segments. Through the CH7513A’s advanced decoding /

encoding algorithm, the input DP/eDP high-speed serialized

video data can be seamlessly converted to LVDS, a popular

display technology for high-speed serial links in mid/large-sized

LCD displays. Leveraging the DP/eDP’s unique source/sink

“Link Training” routine, the CH7513A is capable of instantly

bring up the video display to the LCD when the initialization

process is completed between CH7513A and the graphic chip.

The CH7513A is designed to meet the DisplayPort (DP)

Specification version 1.3 and the Embedded DisplayPort

Specification version 1.4. In the device’s receiver block, which

supports two DP/eDP Main Link Lanes input with data rate

running at either 1.62Gb/s or 2.7Gb/s, can accept RGB digital

formats in either 18-bit 6:6:6 or 24-bit 8:8:8 for LVDS output up

to 1920x1200. To comply with GPU’s new power saving

scheme such as display frame rate reduction, the CH7513A is

equipped with the Dynamic Refresh Rate switching method,

which can automatically reduce to the low refresh rate supported

by the LVDS panel.

The integrated LVDS transmitter supports the single port and

the dual ports LVDS outputs to drive display resolution up to

WUXGA (1920x1200). CH7513A supports panel select by

GPIO[0:3] pins control or writing the chip registers. To reduce

EMI emission, the CH7513A’s LVDS encoder block has

incorporated Spread Spectrum control and its spread percentage

can be adjusted through the internal registers.

The Backlight On/Off and the PWM are two luminance control

functions designed in the CH7513A LVDS power control

module. The brightness control commands sent through AUX

Channel can be dynamically translated by CH7513A and

converted into LCD backlight control signal. The CH7513A will

save the last setting of brightness level into the BOOT ROM and

restore it upon power up. The CH7513A can dynamically adjust

backlight brigntness according to video stream to save power

consumption and it supports OSD display in this way.

The CH7513A will immediately convert the DP/eDP signal to

LVDS output after DP/eDP Link Training is completed. This

feature can be achieved by loading the panel’s EDID and the

CH7513A’s configuration settings in the serial BOOT ROM

connected to the CH7513A. During system power-up and upon

completion of the DP/eDP Link Training through AUX

Channel, CH7513A will generate LVDS signal according to the

panel power-up timing sequencing stored in the BOOT ROM.
