Overview
The TW2968-LA1-CR is an eight-channel video decoder and audio codec designed for surveillance applications. It decodes base-band analog CVBS into digital 8-bit 4:2:2 YCbCr output. The device supports NTSC/PAL standards with WD1 (960H) and D1 formats. Power requirements include a 1.0V digital supply and 3.3V I/analog supply. It operates from a single 27MHz crystal. The component is housed in a 128-pin LQFP package.
Feature Summary
- Integrates eight 10-bit ADCs with analog clamping circuits for composite video input processing.
- Includes ten integrated audio ADCs and one audio DAC supporting multi-channel mixed analog output.
- Features advanced synchronization processing, adaptive comb filtering, and digital sub-carrier PLL for accurate color decoding.
- Supports programmable image enhancement parameters including hue, brightness, saturation, contrast, and sharpness.
Applications
- Video surveillance systems
- Digital video recording equipment
- PTZ camera control interfaces
Procurement Notes
Verify the current lifecycle status as the component is listed as discontinued by the manufacturer. Confirm availability through authorized distributors or secondary market sources. Ensure compatibility with existing board designs requiring the 128-pin LQFP footprint. Check for moisture sensitivity handling requirements during storage and assembly processes.
Selection Notes
Select this component for applications requiring simultaneous decoding of multiple composite video channels with integrated audio processing. It is suitable for systems needing low power consumption and support for both WD1 and D1 resolutions. Consider the 128-pin LQFP package constraints and the specific voltage domain requirements for digital and analog sections.
Part Context
The TW2968 belongs to the Renesas Intersil video decoder family. It is pin-compatible with the TW2964 128-LQFP version. The series is designed for low-power video surveillance environments. It combines video decoding capabilities with audio codec functions in a single integrated circuit solution.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternative components due to the discontinued status.
