Currently, the main video signal conversion chips on the market are not uniform and can be manufactured individually or together with multiple bridge chips. Through the experience of using this project in recent years, we will introduce various types of digital-to-analog conversion chips for your reference, and the performance is relatively stable. In the future, we will update the experience of all types of audio and video signal conversion chips. I also hope to provide you with the opportunity to learn and help you. We welcome many tips ~~ One, the chip solution MS9282 \/ MS9288 AVGA to HDMI, YPbPr\/WII\/RGBS to HDMI MS9282 is an external MCU. The MCU model is variable, which guarantees that the program's storage space is greater than 16K. Performance is very stable because in addition to converters and other products, you can also develop and control programs to make more complex high-end products at the system level. However, the MS9288A is an integrated MCU, and the software has been hardened at the time of shipment and cannot be tried. At present, the WII to HDMI program is mainly nostalgic for the game console WII is a game console product interface, the real signal is similar to YPbPr. We recommend using demo tests to select this prompt solution. Testing is not a problem, so decide how to use it. It is suitable for simple converters and cost-effective products with single functions. Both chips are step solutions that can recover real images sometimes seen in disassembly of many domestic and foreign products, it is relatively stable. Second, the MS1830 \/ MS 1835 VGA to AV\/S video function MS1830 is currently being used in new areas such as drone and wireless image transmission, equipped with the AG6200 chip as a solution from AV to HDMI. The AG6200 is a VGA chip for HDMI. The AG 6200 MS 1830 has hardware reference design data ready for immediate use, and software can also be developed. Built-in SDRAM saves PCB cost and space, and the reputation of similar products is also good. The MS 1835 is an integrated MS 1830 chip with an integrated MCU, and the software has been fixed at the factory and cannot be debugged. At present, most converter box products are profitable. Three, MS 1850 AV for VGA function POP support If you need to test in EVB, 3D decoder noise reduction, OSD function, peripheral BOM is easy, the effect on the screen can use OSD software, manual button to adjust the color contrast amazing! Fourth, MS1858SAV to HDMI function nostalgic game console, retro computer, suitable for other programs, you need to connect the old AV interface device is high quality picture, this function of the motherboard in order to emphasize the quality, built-in MCU. The development cycle is short. 5, ms 1820 chip VGA\/HDMI solution, to SDI (MS1820 GV7700), to HDMI solution VGA (scale), YUV 4 Digital: for analog VGA\/YPbPr\/AV 2: 2 \/ RGB888 and other analog-digital, digital-analog. The MS 1820 is a powerful video signal processor. With display device, VideoScaler zoom, OSD and other functions. It is widely used in low-end and high-end products such as car front, splicing screen, hotel panel, medical equipment, converter and so on. Input support Input signals: RGBS\/VGA analog signal, 24-bit digital RGB\/YUV \/ 16-bit YUV4:2:2\/8-bit BT656-601, such as BT1120. Output, analog VGA\/YPbPr\/AV (NTSC only), digital 24-bit YUV \/ 16-bit YUV4:2:2 \/ RGB4:4: Supports output signals, such as 4. Six, U?? SB Chip Solution for MS 2100E\/MS 2106 AV\/S video Both chips have an MCU built in and the surrounding environment is very simple. The MS 2106 can reach the smallest thumb area. It is widely used in video capture card (video capture), rear view, line recorder, medical endoscope, video ringtone system and other products. The MS2100E is suitable for acquisition cards, on-board programs, the MS2106 is suitable for automotive and medical fields, all compatible systems and screen effects are possible. 7, MS 7024 RGB 888 Digital signal\/VGA\/HDMI AV chip solution The MS 7024 is a great tip. The main entrance accepts digital signals and is compatible with ITU-RBT. 601\/656 Inputs and outputs support AV signals in PAL and NTSC formats. MS 7024 is a DAC-like chip that is used with other chips and is often used as a complementary chip widely used in automotive electronics. In general, these functions basically follow six stages, which is easy to note from start to finish: First, the evaluation stage: project specification parameters, demonstration demonstration, material introduction, etc. Second, hardware design: release reference design data. Three, software support: software development. Four, test patches: Sample application support. Purification of FAE five, small batch production: focus on production. The sixth stage of large-scale production site commissioning
