Overview
The TW2964-LA2-CR is a low-power NTSC/PAL video decoder designed for surveillance. It decodes base-band analog CVBS into digital 8-bit 4:2:2 YCbCr. The device supports WD1 (960H) and D1 compatible decoding with automatic format detection for NTSC and PAL standards. It features four 10-bit ADCs, an adaptive comb filter for Y/C separation, and programmable gain control. Power consumption is minimized via a power-down mode, utilizing 1.0V digital and 3.3V I/O/analog supplies.
Feature Summary
- Supports WD1 and D1 compatible video decoding with automatic standard detection
- Converts analog CVBS to digital 8-bit 4:2:2 YCbCr output
- Integrates four 10-bit ADCs with analog clamping circuits
- Includes high-quality adaptive comb filter for reduced cross-color artifacts
Applications
- Video surveillance systems
- Analog-to-digital video conversion
- Base-band signal processing
Procurement Notes
Verify the specific suffix 'CR' against official Renesas documentation to confirm package type and temperature range. Ensure compatibility with required 1.0V and 3.3V power domains. Confirm availability status as datasheets may indicate end-of-life or limited stock conditions for specific suffixes.
Selection Notes
Select this component when low power consumption is critical for composite video decoding applications. The integrated adaptive comb filter addresses cross-luminance and cross-color issues without external components. Verify that the 8-bit 4:2:2 YCbCr output interface matches the downstream processor requirements.
Part Context
The TW2964 belongs to Renesas' family of video decoders targeting security and monitoring markets. It replaces older discrete decoding solutions by integrating analog front-end, synchronization, and color decoding into a single chip. The LA2 variant typically denotes a specific package configuration within this product line.
Replacement Considerations
Check for direct pin-compatible upgrades within the TW29xx series. Verify if newer revisions offer improved noise immunity or additional channel counts while maintaining the same form factor.
