TW2964-LA2-CR128

Overview

The TW2964-LA2-CR128 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 4H comb filter for Y/C separation, and programmable gain control. Power supplies include 1.0V for digital and 3.3V for I/O/analog, requiring a single 27MHz crystal.

Feature Summary

• Supports WD1 (960H) and D1 compatible video decoding with automatic standard detection
• Integrates four 10-bit ADCs with built-in analog anti-alias filtering
• Utilizes a 4-H adaptive comb filter for high-quality Y/C separation
• Features fully programmable static or automatic gain control for the Y channel

Applications

• Video surveillance systems
• Composite video input applications
• Multi-standard video decoding setups

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature range. Confirm current production status as legacy components may have limited availability. Ensure the 27MHz crystal requirement is integrated into the system design. Check for RoHS compliance details in the latest datasheet revision.

Selection Notes

Select this component for applications requiring low power consumption in composite video decoding. It is suitable for designs needing simultaneous multi-standard support without external format detection logic. Consider the 1.0V digital supply requirement for power management strategies. Evaluate the need for adaptive comb filtering to reduce cross-color artifacts in the final image output.

Part Context

This part belongs to the TW2964 series of video decoders from Renesas Electronics. It is related to the TW2968, which offers eight channels. The TW2964 focuses on four-channel performance with optimized power usage for surveillance environments. It represents a solution for converting analog composite signals to digital formats for further processing.
