Description	FLI8638

1 Description

The FLI8638 offers high integration for advanced applications of Picture-in-Picture (PIP) and Picture-by-Picture (PBP). Two triple ADCs and an integrated video decoder with 3D comb filters complemented by true 10-bit performance provide the highest quality picture for a two-channel application.

Special performance features such as the Faroudja DCDi Cinema video format converter, blue stretch, DDR memory with a read-write picture capacity data of 10 bits per pixel, and the most flexible picture sharpening system in one device provide unparalleled performance. The video quality level that was exclusive to Faroudja Home Theater Systems is now available in a single-chip solution.

The FLI8638 also comprises an integrated Analog Front-End (AFE) that includes two 10-bit ADCs, an integrated analog multiplexer, and a Faroudja Intellicomb™ 3D video decoder. The flexible AFE ensures simple PCB design with direct connections to TV tuners and input video connectors. Thus, the FLI8638, for a single LCD TV chassis, is able to support worldwide standards. For regional variations, only a connector and firmware change are required.

The integrated VBI dataslicer and decoder remove the need for external components resulting in significant cost reduction. The FLI8638 supports many worldwide VBI standards for applications of Teletext, Closed Captioning, V-Chip, and other VBI services.

An embedded microprocessor and a versatile OSD in a single device will facilitate rapid development of a reliable and attractive product. The FLI8638 utilizes the common Cortez family firmware making migration easy and effortless across different hardware platforms within this family.
