1. General Description
The LT8618EX is Lontium’s low power version HD-DVI transmitter based on ClearedEdge™ technology. It supports the 24-bit color depth HD-DVI 1.4 (High Definition Multimedia Interface) specification. They are fully backwoard compatible with Lontium’s first generation HD-DVI transmitter LT8618, and al so pin compatible with Silicon Image SiI9030 and Analogix ANX9030 transmitters. LT8618EX is a high performance, low power part that are specifically designed for HD-Digital cameras, HD-Digital Video Cameras, HD-PMP/MP4 Players, Cell phones, etc. The normal operation power is less than 100mA playing 24bit 1080P content, and the standby power is less than 2mA.
