TW9992AT-NA1-GE

Overview

The TW9992AT-NA1-GE 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 supports single-ended, differential, and pseudo-differential composite video inputs with built-in anti-alias filtering. Key electrical parameters include 1.8V and 3.3V power supplies, 3.3V tolerant I/O, and a typical power consumption of 100mW. It operates with a single 27MHz crystal or supports 24.54MHz and 29.5MHz crystals for high-resolution square pixel formats. The component is housed in a 32-Ld QFN package with wettable flanks and holds AEC-Q100 qualification.

Feature Summary

• Supports software-selectable analog input control for combinations of single-ended and differential CVBS signals
• Integrates advanced image enhancement capabilities including programmable Automatic Contrast Adjustment (ACA) and peaking
• Features integrated short-to-battery and short-to-ground detection tests for automotive safety compliance
• Provides MIPI 1.1 compliant unidirectional output in YUV 422 or RGB565 formats

Applications

• Automotive rear-view camera systems
• Automotive surround view monitoring systems
• Automotive head-up display (HUD) video processing

Procurement Notes

Verify the specific suffix 'AT' indicates AEC-Q100 automotive qualification status as documented. Confirm the package variant includes wettable flanks for enhanced solder joint inspection reliability. Ensure the design supports the required crystal frequencies (27MHz, 24.54MHz, or 29.5MHz) for the target resolution. Validate that the MIPI-CSI2 interface compatibility matches the downstream processor requirements.

Selection Notes

Select this component when automotive-grade reliability and low power consumption are critical for video decoding tasks. The AEC-Q100 qualification makes it suitable for harsh automotive environments. Consider the differential CVBS input capability if signal integrity over long traces is a concern. The integrated short-to-battery/ground detection simplifies system-level safety diagnostics compared to non-automotive alternatives.

Part Context

This part belongs to the Renesas TW9992 series of video decoders. The 'AT' suffix specifically denotes the automotive-qualified version of the TW9992. It is distinct from commercial variants by its adherence to AEC-Q100 standards and inclusion of automotive-specific diagnostic features like short-circuit detection.
