Video Conversion B
This page lists MacroSilicon Video Conversion B series models with selection comparison for conversion between RGB/HD and CVBS/S-Video SD analog video.
This series focuses on single-chip conversion between HD/RGB digital or HD signals and SD composite video. For VGA/YPbPr ↔ HD bridging, see Video Conversion A. Confirm final selection with official datasheets and sample validation.
Model List
| MS1830 | MS1835 | MS1836C | MS1852 | MS1858E |
Quick Selection
| Requirement | Recommended model | Notes |
|---|---|---|
| RGB/VGA → CVBS/S-Video | MS1830 | Integrated SDRAM, 1080P input, OSD, 1/8×–8× scaling |
| RGB/VGA → CVBS/S-Video (zero-config) | MS1835 | Adds integrated MCU vs MS1830 for multi-scenario adaptivity |
| HD → CVBS/S-Video | MS1836C | Single-chip, 1920×1200@60 input; P2P replacement for MS1836S |
| CVBS/S-Video → VGA | MS1852 | Up to 1920×1200@60; replaces MS1850/MS1851 |
| CVBS/S-Video → HD | MS1858E | HD 1.3 output, master/slave modes, analog audio |
Parameter Comparison
| Model | Conversion direction | Input | Output | Max capability | Audio | Video processing | Controller | Package |
|---|---|---|---|---|---|---|---|---|
| MS1830 | RGB → SD analog | RGBHV | CVBS, S-Video | 1080P input | — | OSD; 3D NR; 1/8×–8× scaling; frame-rate conversion | External control; integrated 2 MB SDRAM | LQFP48 (7 mm × 7 mm) |
| MS1835 | RGB → SD analog | RGBHV | CVBS, S-Video | 1080P (incl. interlaced) | — | Same as MS1830; transition/B&W enhancement | Integrated MCU + SDRAM | LQFP48 (7 mm × 7 mm) |
| MS1836C | HD → SD analog | HD | CVBS, S-Video | 1920×1200@60 | Analog stereo + S/PDIF | OSD; 3D NR; 1/8×–8× scaling | Integrated MCU/firmware | QFN-48 (7 mm × 7 mm) |
| MS1852 | SD analog → VGA | CVBS, S-Video | VGA | 1920×1200@60 VGA 1280×720@60 BT.656 | — | Deinterlace; 3D NR; PIP; OSD | Integrated MCU; SPI Flash | QFN-48 (7 mm × 7 mm) |
| MS1858E | SD analog → HD | CVBS, S-Video | HD 1.3 | WUXGA | Analog L/R input | 3D deinterlace; scaling; OSD; frame-rate conversion | Integrated MCU; master/slave (MCUSEL) | QFN-48 (7 mm × 7 mm) |
Replacement Notes
- MS1836C is a P2P replacement for MS1836S; use MS1836C for new designs.
- MS1852 is the recommended new-design part, replacing MS1850 / MS1851.
Selection Notes
- VGA to Video (PC to TV/recording): MS1830 is feature-complete; for plug-and-play multi-scenario use without external MCU setup, choose MS1835.
- HD source to analog monitor/recording: MS1836C integrates HD receive and SD encode with audio and OSD.
- Analog camera / STB to VGA display: MS1852; do not use MS1850/MS1851 in new designs.
- Analog source to HD TV/projector: MS1858E; master mode supports EEPROM customization, slave mode for external I²C control.
- MS1830 vs MS1835: similar signal chain; MS1835 integrates MCU to reduce system software burden, MS1830 requires external control logic.
