描述
LT8712是一个DisplayPort(DP)到HDMI和VGA转换器，设计用于同时连接一个DP源到一个VGA收发器和最多两个HDMI收发器。LT8712集成了一个DP1.2兼容的接收器、一个高速三通道视频DAC和两个HDMI1.4兼容的发射器(发射器0和发射器1)。接收端口集成了CC控制器，当连接到USBType-C源时，该控制器支持DP交替模式。
提供两个数字音频输出接口，12S和SPDIF。都支持8通道LPCM或压缩音频在最大192kHz采样率。
该设备能够自动操作，该操作由集成MCU实现，该MCU使用嵌入式SPI闪存进行微码处理。系统控制也可通过使用专用配置12C从站接口。
该LT8712提供两种封装类型，LT8712和LT8712B。LT8712是带有ePad的128引脚LOFP封装，而LT8712B是144球LFBGA封装。两者的工作温度范围均超过-40°C至+85'C。

DescriptionThe LT8712 is a DisplayPort(DP) to HDMI and VGAconverter, designed to connect a DP source to a VGA sinkand up to two HDMI sinks simultaneously. The LT8712integrates a DP 1.2 compliant receiver, a high-speedtriple-channel video DAC and two HDMI 1.4 complianttransmitters (transmitter 0 and transmitter 1). The receiverport integrates a CC controller which enables DPAlternate Mode support when connected to a USB Type-Csource.Two digital audio output interfaces are available, tell 18171547226,I2S andSPDIF. Both support 8-ch LPCM or compressed audio atmaximum 192kHz sample rate.The device is capable of automatic operation that isenabled by an integrated MCU that uses an embeddedSPI flash for microcode. System control is also availablethrough the use of a dedicated configuration I2C slaveinterface.The LT8712 is provided in two package types, LT8712and LT8712B. LT8712 is a 128-lead LQFP package withePad and LT8712B is a 144-ball LFBGA package. Bothare specified over -40℃ to +85℃ operating temperaturerange.
