| RN6266: Four Channel Video Decoder |
| |
| Features |
- High performance ADC with automatic gain control (AGC) offers 10-bit resolution for superior picture resolution and sharpness
- ADC sampling rate up to 54 MHz for best color and image transient response
- Fully differential pre-processing and AGC (250mV - 1.8V) for best S/N performance
- Proprietary fast and robust video synchronization with accurate clamping and gain control
- Low jitter PLL (50ps peak-to-peak) for accurate color carrier phase acquisition
- Automatic detection of NTSC and PAL variants and decoding support
- Support NTSC (J,M,4.43), PAL (B, D, G, H, I, M, N, Nc) CVBS input
- 2D 5-line comb filter provides the high quality video decoding of composite video signal for artifact-free Y/C separation
- True 10-bit processing for color space conversion, brightness/contrast/saturation/hue control, and color correction for best performance
- Vertical and horizontal cropping
- Support standard ITU-R BT.656 format and two/four channel D1 pixel interleaved format output
- User selectable 10bit/8bit ITU-R BT.656 YCbCr 4:2:2 format digital outputs
- Two, four, eight or twelve channel CIF/QCIF pixel interleaved output format is supported through the programmable down scaler
- Four user selectable 0/6.75/13.5/27/54/108 MHz clock outputs with phase and delay adjustments
- Built-in single channel video encoder for CVS or S-video output
- Integrated audio codec supports four audio ADCs, one audio DAC, audio mute detection function, audio recording/playback serial interface with standard/modified I2S/TDM master/slave protocol, and up to four RN6266 audio cascade connection
- Support 8/16-bit linear (PCM) audio encoding/decoding and 8 bit A-law/µ-law encoding/decoding
- Programmable audio sampling rate (8/16/32/44.1/48 KHz)
- I2C interface for control and status registers
- Only requires a single 27 MHz crystal or a 27/54/108 MHz clock source on XIN pin directly
- Industrial temperature range from -40°C to 85°C
- 1.8V and 3.3V power supplies
- 128 pin LQFP package (14 mm x 14 mm)
