NXP SAA8510移動多媒體解決方案
NXP 公司的SAA8510移動多媒體處理器為手機和其它手提設備而設計，它能把數(shù)字視頻信號轉換成稿質量的模擬電視信號，并在 NTSC 和PAL TV上顯示，它不需要特別的時鐘或電源。SAA8510能使任何移動設備輸出電視，并有標準的接口。它支持的輸入格式包括RGB888, RGB666, RGB565, YUV422和YUV420。本文給出了SAA8510的主要性能，以及SAA8510系統(tǒng)應用電路圖。
NXP mobile multimedia processor SAA8510
Designed for use in mobile phones and other portable devices, this processor converts digital video signals into a high-quality analog TV signal that can be displayed on NTSC and PAL TV sets worldwide. It requires no specific clock or voltage supplies, and can be addressed as a simple RAM-based display controller.
The SAA8510 enables TV-out on any mobile device that has a standard LCD interface. The 8/16-bit parallel MIPI DBI-2 host interface lets the SAA8510 be addressed as a simple RAM-based display controller, so there are no real-time constraints on the host. In debug mode, the host interface provides direct access to all registers and the internal 4-Mbit frame buffer.
Supported bbbbb bbbbats are RGB888, RGB666, RGB565, YUV422, and YUV420 for resolutions from 2 x 2 pixels to a maximum width/height of 864 pixels. (The internal SRAM holds a YUV420 frame buffer of 12 bits per pixel, so any image can be buffered with a width/height of between 2 and 864 pixels, as long as the total image size does not exceed 4 Mbits.) The bbbbb frame rate can vary from zero (still picture) to 30 frames per second.
For a simpler design with a lower component count, bbbbbded PLLs let the processor operate based on an bbbbb clock of 19.2, 26, 27, or 38.4 MHz. There’s no need for an external 27-MHz oscillator.
主要特性：
MIPI DBI-2 host interface
Worldwide support for PAL and NTSC
4-Mbit bbbbbded frame buffer
Supports all common mobile resolutions, including VGA @ 30 fps
Supports MacroVision copy protection and VBI data insertion
Excellent output quality based on a rich filter set and polyphase scalers
Advanced power management
Fully integrated solution requires no external oscillator or CVBS drivers
Smallest package on the market: TFBGA48 (4 x 4 mm, 0.4 pitch)
The TV-out interface supports PAL and NTSC CVBS output bbbbats compliant with ITU-R BT.1700 and SMPTE 170M standards. The analog signal is generated by an bbbbbded 10-bit DAC and terminated at 75 Ω, so no external drivers are required.
The processor supports VBI data insertion at 4:3, 14:9, and 16:9 aspect ratios. It also supports MacroVision copy protection (as a factory bond-out option), and CGMS-A, APS, and ASD inbbbbation as described in EN300-294 and IEC61880.
Housed in a TFBGA48 package with a 0.4 pitch and a footprint of only 4 x 4 mm, the SAA8510 is the smallest solution of its kind on the market. Moreover, the package is “dark green”, meaning it’s halogen-free and complies with the RoHS directive.
