TW2868-LA1-CR

Overview

The TW2868-LA1-CR is an integrated circuit video decoder manufactured by Renesas Electronics Corporation. It features eight high-quality NTSC/PAL/SECAM video decoders that convert analog composite video signals to digital component YCbCr data for security applications. Each channel includes a 10-bit ADC, proprietary clamp and gain controllers, and utilizes a 4H comb filter to separate luminance and chrominance. The device also incorporates one NTSC/PAL video encoder with two 10-bit DACs to support CVBS and YC outputs. Additionally, it contains an audio CODEC with ten audio ADCs and one DAC. The component is housed in a 128-LQFP (14x14) package.

Feature Summary

• Eight-channel video decoding with 10-bit ADC resolution
• Integrated NTSC/PAL video encoder with dual 10-bit DACs
• Built-in audio CODEC supporting multi-channel processing
• Image enhancement techniques including IF compensation and programmable peaking

Applications

• Security surveillance systems
• Video monitoring equipment
• Analog-to-digital video conversion modules

Procurement Notes

Verify the exact suffix against official Renesas documentation, as LA1 and LA2 variants may differ in pinout or configuration. Confirm current availability status, as this series has faced end-of-life notices. Ensure compliance with RoHS3 specifications and check moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when eight simultaneous analog video inputs require digitization into YCbCr format. Consider the integrated encoder if composite output is needed alongside decoding. Evaluate the audio codec capabilities if synchronized audio processing is required within the same system architecture.

Part Context

This part belongs to the TW2868 family of video decoders and encoders designed specifically for security applications. It serves as a central processing unit for converting multiple analog camera feeds into digital formats suitable for recording or transmission systems.

Replacement Considerations

Direct substitutes include the TW2866-LC1-CR. Verify functional equivalence regarding channel count and interface compatibility before replacement.
