LT9211C

1. Description

LT9211C is a high performance convertor which interconverts among MIPI DSI/CSI-2, Dual-Port LVDS and TTL except for 24bit RGB TTL to 24bit RGB TTL.

The conversion between 2-port 10-bit LVDS and 24bit RGB TTL is not recommended. LT9211C deserializes input MIPI/LVDS/TTL video data, decodes packets, and converts the formatted video data stream to MIPI/LVDS/TTL transmitter output between AP and mobile display panel or camera. 

LT9211C can be used as 2-port MIPI/LVDS repeater which support maximum 12.5dB input equalization and programmable pre-emphasis to improve performance.

LT9211C can also be used as MIPI/LVDS switch and splitter. However, for MIPI CSI RAW format, it must be continuous clock mode.

Except TTL input or output, VCCIO could be 1.8V. In TTL input applications, VCCIO voltage must be greater than or equal to TTL input high voltage level.

TTL output voltage level is determined by VCCIO, for resolutions above 1080P60Hz, 3.3V is recommended for VCCIO.

LT8918

1. 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.
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.
