TW9900-TA1-GRT

Overview

The TW9900-TA1-GRT is a low-power NTSC/PAL/SECAM video decoder designed for portable applications. It decodes baseband analog CVBS or S-video signals into digital 8-bit 4:2:2 YCbCr output in BT.656 format. The device operates with a single 27MHz crystal and utilizes 1.8V for analog/digital supplies and 3.3V for I/O. Typical power consumption is under 100mW, with further reduction via power-down mode. It features a 2D comb filter for Y/C separation and advanced synchronization circuitry. The component is housed in a 32-pin QFN package (4.0 x 4.0 x 0.90 mm) with a 0.4 mm pitch.

Feature Summary

• Integrated adaptive 4H comb filter for high-quality Y/C separation to reduce cross-color and cross-luminance artifacts.
• Advanced synchronization processing capable of producing stable pictures from non-standard video signals.
• Supports multiple analog video standards including NTSC M, PAL BGHI/M/N, and SECAM using a single crystal reference.

Applications

• Portable consumer electronics requiring low power video decoding
• Systems utilizing composite or S-video inputs
• Devices requiring digital 4:2:2 YCbCr output interfaces

Procurement Notes

Verify the specific suffix TA1-GRT against official Renesas documentation to confirm package type and reel configuration. Confirm end-of-life status and last-time-buy dates through authorized distributors. Ensure moisture sensitivity level (MSL 3) handling requirements are met during storage and assembly processes.

Selection Notes

Select this component when a low-power solution for NTSC/PAL/SECAM decoding is required for portable devices. Verify that the system can accommodate the 1.8V analog/digital supply and 3.3V I/O voltage levels. Ensure the application benefits from the integrated 2D comb filter and does not require higher-performance 3D filtering options found in other series members.

Part Context

This part belongs to the TW9900 series of video decoders manufactured by Renesas Electronics (formerly Intersil). The series targets portable applications with a focus on minimizing power consumption while maintaining standard video decoding capabilities. The TW9900-TA1-GRT represents a specific packaging and tape-and-reel variant within this product line.

Replacement Considerations

Check for direct pin-compatible replacements within the TW9900 family. Verify if newer Renesas video decoder models offer backward compatibility. Consult distributor databases for equivalent parts from other manufacturers supporting similar video standards and interface protocols.
