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. 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. Each input/output

LVDS interface is equipped with 4/1 pairs of differential

signal buses to support video data and clock. The builtin dithering mechanism can be applied to approximate

true 24-bit color video data if system manufacturers use

less expensive 18-bit panels. Conversely, if input data is

only 18-bit color, the simulation to 24-bit color for highend 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

 The device is fully programmable through serial port

or can automatically load firmware from Chrontel

Boot ROM (CH9904)

 Offered in 88-pin QFN package

APPLICATIONS

 Netbooks

 MIDs

 Tablet PCs

 Industrial PCs

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.
