The CH7036 is specifically designed for Consumer Electronics
Devices and Personal Computers that require High Definition
(HD) Content video playback on the external displays such as
HDMI/DVI monitors.
The CH7036’s HDMI transmitter is designed to support 1080p
HDTV and the HDMI repeater function. For desktop monitors
that do not have the HDMI input, the CH7036 has the capability
to disable HDMI mode and output DVI signal or analog RGB
signal (VGA). To support multi-display, the CH7036 can output
either HDM/DVI or Analog RGB signals together with LVDS
signal pass-through.
The CH7036’s single channel LVDS receiver/transmitter
complies with the SPWG specification, a popular LVDS
standard used by panel manufacturers.
LVDS interface is equipped with 4/1 pairs of differential signal
buses to support video data and clock.
mechanism can be applied to approximate true 24-bit color
video data if system manufacturers use less expensive 18-bit
panels.
simulation to 24-bit color for high-end TFT LCD is also
supported.
The device’s LVDS receiver can accept maximum video clock
frequency for up to 85MHz or 1366x768 resolution in 24-bit
color per pixel. A powerful scaling engine working together
with other video processing circuits, will convert the captured
LVDS signal stored in the internal SDRAM into High
Definition Content video data. The built-in mixer will combine
this HD digital RGB signal with decoded audio stream into
HDMI format data, which will be serialized for output display
by the CH7036 TMDS encoder.
The CH7036 supports both SPDIF and 2-channel I2S digital
audio inputs. Its high fidelity audio decoder engine has the
capability of sampling audio frequencies for up to 192kHz for 2
channels.
Utilizing its high speed internal frame buffer, the CH7036’s
scaling engine can increase the flexibility of the screen display.
The video enhancement includes resizing the HDMI/DVI and
RGB output display resolution, performing Frame Rate
Conversion a well as rotating display orientation. Other video
fine tuning, such as brightness control or contrast adjustment
can be used to improve the display on the analog RGB monitor.
When CH7036 is powered up, its MCU is able to automatically
execute the device configuration software in the device’s
internal memory. When the firmware in the memory is
programmed to support EDID communication and HPD, the
MCU will toggle DDC bus lines to retrieve the display timing
from the HDMI/DVI monitor if HPD is asserted. Furthermore
an interrupt signal can be generated by MCU to host while the
CH7036’s HPD is high.
The CH7036 supports the optional HDCP feature for preventing
illegally copy High Definition Contented media.
