Description

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 7.5mmx7.5mm QFN64 package. This package is RoHS compliant and specified to operate from -40°C to +85°C.
