龍迅LT8918是一顆低成本RGB轉MIPI功能的視頻轉換芯片 芯片的功能框架圖如下： The Lontium LT8918 is a high performance MIPIDSI/CSI-2 transmitter for mobile display panel or camera application. The TTL input of LT8918 supports both 24-bit RGB and BT656/1120 video format under either SDR or DDR sampling. The maximum input pixel clock frequency is SDR 148.5MHz or DDR 74.25MHz for 1080P@60Hz high-end mobile display or video capture application. For MIPI DSI/CSI-2 output, LT8918 features a single port MIPI DSI or CSI-2 transmitter with 1 high-speed clock lane and 1~4 configurable high-speed data lanes operating at maximum 1.5Gb/s/lane, which can support a total bandwidth of up to 6Gb/s. LT8918 supports both Non-Burst and Burst DSI video data transferring, as well as Command Mode through Lane-0. The LT8918 is fabricated in advanced CMOS process and implemented in a small outline 7.5mm x 7.5mm QFN64 package. This package is RoHS compliant and specified to operate from -40°C to +85°C. 2.1 Application Mobile systems Cellular handsets Digital video cameras Digital still cameras Tablet PC, Notebook PC Car Display and Camera System 2.2 Features RGB Input Support 24-bit RGB and BT656/BT1120 Input Support both SDR and DDR Data Sampling Programmable Rising/Falling Edge Clock Input Support up to 74.25MHz DDR or 148.5MHz SDR Clock Input Support both 1.8V and 3.3V Input Voltage Level Single-Port MIPI DSI Transmitter Compliant with DCS1.02, D-PHY1.1 & DSI1.02 1 Clock Lane and 1~4 Configurable Data Lanes 80Mb/s~1.5Gb/s per Data Lane Resolution Up to 1080P 60Hz Data Lane and Polarity Swapping Both Non-Burst and Burst Video Mode Supported Command Mode through Lane-0 Supported Support RGB666, Loosely RGB666, RGB888, RGB565, 16-bit YCbCr4:2:2, 24-bit YCbCr 4:2:2 Video Format Single-Port MIPI CSI-2 Transmitter Compliant with D-PHY1.1 & CSI-2 1.0 1 Clock Lane and 1~4 Configurable Data Lanes 80Mb/s~1.5Gb/s per Data Lane Resolution Up to 1080P 60Hz Data Lane and Polarity Swapping Support RGB565, RGB666, RGB888, 8-bit YUV422 Video Format Miscellaneous 1.8V Single Supply Power Support 100KHz and 400KHz I2C slave Support SPI slave External 25MHz Crystal Reference Clock Temperature Range: -400 C ~ +850 C Packaged in QFN64 7.5mm x 7.5mm and BGA81 5mm x 5m 可以免費提供完整的設計資料及樣品，專業的FAE團隊提供現場技術支持服務！ |
