Comb Filter Front-End Processors

Related Information

Comb filter front-end processors from Toshiba provide superior picture quality compared to competitive solutions and value through integration of digital comb filters, color decoders, memory, and image processors into a single IC. The devices reduce the cost and design complexity of advanced analog and digital television, set-top box and other broadcast video equipment since separate DRAM is not required. Toshiba plans to continue to expand its product family with increased levels of integration and new features.

Product Family

The TC90101FG is Toshiba's first 3-line comb filter front-end processor featuring proprietary line comb algorithms for superior picture quality compared to previous generation Toshiba comb filter front-end processors. It provides high-quality analog video luma and chroma separation, multi-standard color decoding, and advanced picture improvement functions such as sharpness, LTI and CTI. The digital YCbCr output provides a high-picture-quality interface to back-end digital video processors. The device is equipped with a 10-bit analog-to-digital (A/D) converter for composite video or luma input signals.

The TC90103AFG is a second-generation, high-performance 3D comb filter front-end processor designed for advanced analog and digital televisions, audio/video systems, set-top-boxes and other video processing systems. The TC90103AFG integrates a 3D comb filter for NTSC, multi-standard 3L filter, 3D noise reduction, digital multi-standard decoder and 5-Mbits of DRAM as frame memory in a compact 144-pin LQFP package to provide a complete solution for analog/video processing.
