Introduction

The LT9211 is a high-performance converter that supports bidirectional conversion between MIPI DSI/CSI-2/dual-port LVDS and TTL (except 24-bit TTL to 24-bit TTL), with support for both SYNC and DE modes. The device deserializes input MIPI/LVDS/TTL video data, decodes packets, and converts the formatted video data stream to MIPI/LVDS/TTL transmitter output for connecting application processors to mobile display panels or cameras. It can be used as a dual-port MIPI/LVDS repeater, supporting up to 14dB input equalization and programmable pre-emphasis for enhanced performance. In addition, the LT9211 can also function as a MIPI/LVDS multiplexer and demultiplexer. For MIPI repeater, multiplexer, and demultiplexer applications, it also supports CSI RAW format and continuous clock. The device is manufactured using advanced CMOS process technology and is housed in a 7.5×7.5mm QFN64 package. This package is RoHS compliant with an operating temperature range of -40℃ ~ +85℃.
