TW9992AT-NA1-GET

Overview

The TW9992AT-NA1-GET is a low-power NTSC/PAL analog video decoder designed for automotive applications. It features differential CVBS inputs and a MIPI-CSI2 output interface. The device operates on a single 27MHz crystal, supporting 24.54MHz and 29.5MHz formats for high-resolution square pixels. It utilizes a 32-Ld QFN package with wettable flanks and is AEC-Q100 qualified. Typical power consumption is 100mW.

Feature Summary

• Supports single-ended, differential, and pseudo-differential composite video inputs with software-selectable control.
• Integrates advanced image enhancement including Automatic Contrast Adjustment (ACA), peaking, and CTI correction.
• Includes built-in short-to-battery and short-to-ground detection tests for automotive safety compliance.
• Outputs YUV 422 or RGB565 data via a MIPI 1.1 compliant unidirectional CSI-2 interface.

Applications

• Automotive rear-view camera systems
• Surround view monitoring systems
• In-car infotainment video processing

Procurement Notes

Verify the specific suffix 'GET' indicates tape-and-reel packaging when ordering. Confirm AEC-Q100 qualification status for the target automotive application. Ensure the design supports the required 32-Ld QFN footprint with wettable flank solderability requirements. Check for updated datasheet revisions to confirm pinout compatibility.

Selection Notes

Select this component for designs requiring MIPI-CSI2 integration directly from an analog video source. It is suitable for environments needing robust sync detection for non-standard signals. Consider the 1.8V/3.3V dual supply requirement and 3.3V tolerant I/O levels. Verify that the typical 100mW power budget fits the thermal constraints of the enclosure.

Part Context

This part belongs to the TW9992 series of video decoders from Renesas Electronics. It is specifically engineered for the automotive sector, distinguishing itself through AEC-Q100 qualification and integrated fault detection mechanisms not typically found in consumer-grade decoders. The series focuses on converting analog composite video into digital formats for modern display processors.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative Renesas video decoders based on MIPI-CSI2 output support and automotive qualification requirements.
