1. General Description

The LT8619 is Lontium’s high performance HDMI receiver chip based on ClearEdge Technology, compliant with the HDMI 1.4(High Definition Multimedia Interface) specification. The RGB output ports can support RGB888/RGB666/RGB565 format and the output resolution can support up to 4Kx2K resolution. With programmable scalar, LT8619 can do scaling up and down within 1080P 60Hz resolution. LT8619 integrates MCU and it has 10 GPIOs. For easy implementation of a multi-media system, LT8619 supports 8-channel high quality I2S audio or SPDIF audio output. It integrates 4M bits nor-flash inside (option), and also you can use external nor-flash by SPI interface for compatibility.
