TW2960-LA1-CR

Overview

The TW2960-LA1-CR is a four-channel video decoder and audio codec integrated circuit manufactured by Renesas Electronics Corporation. It supports NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination, PAL 60) standards with automatic format detection. The device features four 10-bit analog-to-digital converters for CVBS input, software-selectable analog inputs allowing two CVBS per ADC, and a built-in analog anti-alias filter. It includes five audio ADCs and one audio DAC, supporting PCM 8/16-bit and u-Law/A-Law 8-bit formats. The IC operates on a 1.8V/3.3V power supply with 3.3V tolerant I/O, housed in a 100-pin LQFP package.

Feature Summary

• Four-channel video decoding with 4-H adaptive comb filter Y/C separation and image enhancement capabilities
• Integrated audio processing with five ADCs and one DAC supporting multiple digital interfaces
• Automatic standard detection for NTSC and PAL variants with programmable image controls
• Low power consumption with dedicated power save and power down modes

Applications

• Video surveillance systems requiring multi-channel composite video input
• Security DVR/NVR platforms needing simultaneous audio and video digitization
• Broadcast equipment utilizing ITU-R BT.656 or time-multiplexed digital outputs

Procurement Notes

Verify the specific ordering suffix LA1-CR against the manufacturer's current datasheet to confirm pinout compatibility and environmental compliance status. Confirm that the component remains active in the production lifecycle before finalizing procurement plans, as discontinuation notices may affect long-term availability.

Selection Notes

Select this component when designing systems requiring four independent video channels with integrated audio capture in a single package. Ensure the design accommodates the 100-pin LQFP footprint and provides a single 36MHz crystal oscillator for clock generation across all supported video standards.

Part Context

This part belongs to the TW2960 series of video decoders and audio codecs originally developed by Intersil Corporation, which was subsequently acquired by Renesas Electronics. The series is designed for high-performance security applications requiring low power consumption and comprehensive analog-to-digital conversion capabilities for both video and audio signals.

Replacement Considerations

Check for direct pin-compatible replacements within the TW2960 family or newer generations from Renesas. Verify functional equivalence regarding channel count, supported video standards, and audio codec specifications before substituting.
