Single-chip TV solution reduces development effort, time

Micronas announced a single-chip TV solution with dedicated features such as 3D comb filter, component input for HDTV signals, and LVDS outputs.

Touted to be a break-through in full-featured LCD-TV solutions, the VCT 69xyP family starts with the Eco Version, which addresses smaller LCD-TV requirements with a 2D color decoder, a line-based de-interlacer and 10 pages of teletext. The basic version targets mid-size LCD panels, and offers a motion-adaptive frame-based de-interlacer and 500 pages of teletext, while the Premium Version features a 3D-color decoder, a motion-adaptive frame-based de-interlacer and 1000 pages of teletext.

According to Hermann Zibold, Director Business Line Value TV at Micronas, their customers needed to reduce development effort and time, while covering a broad range of products. "With these targets in mind, we [Micronas] designed the VCT 69xyP, a family of pin- and software-compatible ICs which exceed current integration levels by far," he said.

"We integrated all essential TV functions, including memory, into one QFP package. The VCT 69xyP has a multi-standard video decoder with 3D comb filter, motion adaptive de-interlacer and scaler, micro-controller and graphics processor, stereo decoder and audio sound processor, and LVDS transmitters to directly drive an LCD panel," Zibold added.

All derivatives of the VCT 69xyP offer full input and output connectivity for peripheral audio and video signals, making the use of additional A/V switches obsolete, the company said. An analog PC input and component video inputs for HDTV formats such as 1080i and 720p are supported. The VCT 69xyP supports the new European HD-Ready label for WXGA FPD-TVs via a 24bit RGB interface and an I?S audio input connected to an external DVI or HDMI receiver IC, and comes with a full set of picture improvement features, including Dynamic Contrast Enhancement (DCE), Luminance- and Color Transient Improvements (LTI /CTI) and Nonlinear Color Enhancement (NCE).

According to Micronas, picture performance is further enhanced with its truD technology. Included in the Micronas FRC 942xA, truD delivers two unique features: vector-based motion compensation de-interlacing and film de-juddering. When combined with the VCT 69xyP, it delivers unparalleled picture quality in large flat panel displays, explained the company.

VCT 69xyP versions with 2-channel LVDS or 30-bit TTL outputs enable the use of any LCD or PDP panels up to WXGA and SXGA resolutions. Progressive-scan and 100Hz CRTs are also supported by using the analog RGB output version of the VCT 69xyP with the Micronas DDP 331xC deflection controller.

The audio part of the VCT 69xyP offers multi-standard sound decoding and complete baseband processing. A separate headphone channel and a five-band equalizer are only two examples of the wide audio feature set. Additional audio features such as Virtual Dolby Surround, BBE, SRS TruSurround XT are optionally available too.

Packaged in a 208-pin LQFP, the VCT 69xyP does not require any additional external RAM or flash, allowing low-cost 2-layer PCB designs. This new chip will sample in Q2 2005. Evaluation boards, development tools and a comprehensive software package will be also be available. Customers currently using Micronas solutions such as the VCT 49xyI will be able to reuse a substantial part of their existing software.
