Chrontel CH7038B is an innovative display interface

product designed for embedded systems, consumer

electronics and computing in which conversions among

multiple high definition video/audio formats are required.

Built in with multiple differential receivers and

transmitters, a flexible scaling/overlay engine and

easy-to-use audio interfaces, the CH7038B can drive LCD

panels through either a single or dual channel LVDS/TTL

interface or a 1/2 lane DisplayPort interface. It can also

simultaneously output to external displays using standards

such as HDMI/DVI, YPbPr, VGA, CVBS or S-Video.

This device will help manufactures reduce design costs,

accelerate time-to-market and expand product features for

better user’s experience.

The CH7038B has four input and four output ports to

supports multiple display standards. Some ports are

multiplexed with different signal types to reduce pin

count. For example, the 24-bit wide digital port can be

programmed to receive LVDS or TTL signals and

supports various formats like RGB, BT1120, BT656, etc.

while the 8-bit port can accept HDMI or BT656 inputs.

The 2 Lane DP / eDP port stands alone because of its high

data transfer rate. The lower speed SPI port can interface

to external micro controller to display selectively

refreshed data.

A powerful per pixel scaler engine is integrated inside the

CH7038B. Together with its stacked 64Mb SDRAM, the

scaler can process input resolutions up to 1080P and

perform Frame Rate Conversion, Image Rotation/Flip and

flexible Video Zoom. It can overlay a scaled video onto

another bypassed graphics stream to achieve

picture-in-picture display. This would allow user to view

two display contents on a single monitor. The scaler also

supports chroma-key to overlay irregularly shaped video

with monochrome background onto a second video

stream. Though its MCU and SPI interface, external micro

controller can input complex OSD data into the overlay

buffer using the selective refresh mode. These features

make CH7038B an ideal solution to display multiple video

sources onto multiple displays.

Through a 4x2 input switch matrix, the device’s scaler can

be configured to simultaneously accept two separated

video formats with independent display timing. The input

combination can be mixed among the

TTL/BT1120/LVDS, the DP/eDP, the HDMI/BT656 and

the SPI interface input in either RGB format (RGB-565,

RGB-666 or RGB-888 and etc.) or YCrCb format (ITU-R

? Support 2 channel I2S digital audio input and 8(7.1)

channel output for up to 24-bit data stream

(32kHz/8ch, 44.1kHz/8ch, 48kHz/8ch,

88.2kHz/8ch, 96kHz/8ch, 176.4kHz/8ch and

192kHz/8ch)

601/656 and BT1120). A 2x4 output switch matrix can be

programmed to drive the various output ports

simultaneously with two kinds of independent timing.

The CH7038B supports 3D data structures defined by DP

and HDMI standards. The device can translate and repack

3D data when DP signals are converted to HDMI and vice

versa. 3D data can also be displayed as R/L frame via its

LVDS output.

The CH7038B’s DisplayPort receiver and transmitter are

designed to comply with DisplayPort Specification 1.2

and Embedded DisplayPort (eDP) Specification version

1.3. It provides support for one or two Main Link lanes

with data rate running at 1.62Gb/s or 2.7Gb/s. To further

optimize the display quality and power dissipation, this

device is equipped with seamless display refresh rate

switching and progressive to interlace timing switching

capabilities.

The CH7038B’s HDMI receiver and transmitter are

designed to meet HDMI Specification 1.4 and DVI

Specification 1.0. The transmitter performs serialization

and transmission of video/audio data up to 4Kx2K with

the internal powerful scaler engine. On-chip HDCP cipher

engine can be activated to protect the high definition

media content.

Dual channel LVDS receiver and transmitter are

incorporated into the CH7038B. The Panel protection

mechanism is also built in to switch off the LCD instantly

through device’s automated panel on/off sequences if

input data is missing or unstable. The backlight on/off

control can be configured through programming internal

registers. A built-in PWM generator can be used to adjust

display brightness and dimming of the LCD. Dithering

algorithm is implemented on chip in support of 18-bits

LCD panels.

To support legacy analog displays, three

high-performance 9-bit DACs along with separate

horizontal and vertical sync outputs are used. CH7038B

can output analog RGB signals for VGA monitor, YPrPb

for HDTV and CVBS / S-Video for SDTV.

To support local digital audio input and output, the device

has both SPDIF and 2-channel I2S digital audio interfaces.

Like the video signal path, the audio path can take inputs

from DP, HDMI, SPDIF and I2S sources and repack the

data for the chosen outputs. Its high fidelity audio engine

can handle sampling frequency for up to 192kS/s of stereo

and 7.1 audio. The SPDIF interface supports PCM

encoded data and compressed audio including Dolby

Digital and DTS.

In summary, the CH7038B is a general purpose display

interface converter. It is designed to handle both advanced

and legacy display interface standards. It can be used in

universal docking stations for phones, tablets, personal

computers, OTT and IOT devices for both the office and

the home markets.
