描述
LT8712是一個(gè)DisplayPort(DP)到HDMI和VGA轉(zhuǎn)換器，設(shè)計(jì)用于同時(shí)連接一個(gè)DP源到一個(gè)VGA收發(fā)器和最多兩個(gè)HDMI收發(fā)器。LT8712集成了一個(gè)DP1.2兼容的接收器、一個(gè)高速三通道視頻DAC和兩個(gè)HDMI1.4兼容的發(fā)射器(發(fā)射器0和發(fā)射器1)。接收端口集成了CC控制器，當(dāng)連接到USBType-C源時(shí)，該控制器支持DP交替模式。
提供兩個(gè)數(shù)字音頻輸出接口，12S和SPDIF。都支持8通道LPCM或壓縮音頻在最大192kHz采樣率。
該設(shè)備能夠自動(dòng)操作，該操作由集成MCU實(shí)現(xiàn)，該MCU使用嵌入式SPI閃存進(jìn)行微碼處理。系統(tǒng)控制也可通過使用專用配置12C從站接口。
該LT8712提供兩種封裝類型，LT8712和LT8712B。LT8712是帶有ePad的128引腳LOFP封裝，而LT8712B是144球LFBGA封裝。兩者的工作溫度范圍均超過-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.
