CVBS to HDMI solution description

The basic specifications of this program are as follows:

Input signal support:

CVBS: PAL720x576 NTSC720x480

Output signal support:

HDMI: 720x480 720x576 1280x720 60Hz 1280x1024 60Hz 1280x1024 60Hz 1360x768 60Hz 1600x1200 60Hz 1680x1050 60Hz 1920x1080 60Hz

Connector function definition: (subject to the latest PCB document of Chipav)

P3: HDMI output

J1: Power 5V input

SW1: Output resolution switch

P1: CVBS input

Instructions:

Before the PCB solution board is powered on, first plug the CVBS signal source into the P1 interface through the CVBS line, and then connect to the P3 interface through the HDMI line.

Finally, plug in the 5V power supply (Micro USB interface), and the board can light up and work normally.

When the power is on, you can switch the output resolution (720P/1080P) through SW1.

This solution consists of four main chips, and the process is as follows:

GM7150: Decode CVBS signal and output digital signal to CV2880.

CV2880: Scale the resolution of the input signal, and output the digital signal to CV8788.

CV8788: The encoded digital signal is HDMI signal output.

N76E003: The controller of the overall solution.
