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.
