TW9966AT-LC1-GR

Overview

The TW9966AT-LC1-GR is a four-channel analog video decoder and encoder integrated circuit manufactured by Renesas Electronics Corporation. Designed for automotive applications, it accepts NTSC, PAL, and SECAM standards with auto-detection capabilities. The device integrates four video analog anti-aliasing filters and 10-bit CMOS ADCs, alongside high-performance adaptive 4H comb filters. It features an integrated five audio ADCs and one audio DAC, supporting I2S/DSP interfaces. The component operates on 1.8V and 3.3V supplies, utilizes an I2C control interface, and is housed in a 128-lead LQFP package.

Feature Summary

• Integrates four high-quality video decoders with 10-bit ADCs and proprietary clamp/gain controllers for automotive use
• Includes one NTSC/PAL video encoder with two 10-bit DACs to support CVBS and YC outputs
• Features integrated audio CODEC with multichannel mixed analog output and programmable sample rates
• Supports standard ITU-R BT.656 format or time-multiplexed output at specified frequencies

Applications

• Automotive rear-view camera systems
• In-car entertainment displays
• Vehicle monitoring and surveillance units

Procurement Notes

Verify the specific suffix LC1 against official Renesas documentation to confirm pinout and electrical characteristics. Ensure the component meets AEC-Q100 qualification requirements for your target automotive environment. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when a multi-channel solution combining video decoding and encoding is required for automotive grade reliability. Consider the 128-lead LQFP package size constraints during PCB layout. Verify that the system architecture supports the I2C control interface and the required audio sampling rates for the intended application.

Part Context

This part belongs to the TW9966 series of video processing ICs from Renesas. It is specifically engineered for automotive environments, offering robust signal processing for composite video inputs. The series typically includes variants with different packaging or thermal ratings, but all share the core functionality of converting analog video to digital YCbCr data.

Replacement Considerations

Check for direct cross-references in Renesas' obsolescence notices. Alternative solutions may require significant schematic redesign due to differences in pin configurations or power supply requirements. Consult the manufacturer for validated substitute part numbers before proceeding.
