LT8712EXC

1. 描述

LT8712EXC是一款高性能的Type-C/DP1.2到HDMI2.0/VGA轉換器，設計用于將USB Type-C源或DP1.2源同時連接到VGA接收器和HDMI2.0接收器。

LT8712EXC集成了一個符合DP1.2的接收機(MST能力)，一個高速三通道視頻DAC和一個符合HDMI2.0的發射機。CC通信采用兩個CC控制器，分別為上游Type-C端口和下游Type-C端口，實現DP Alt模式和供電功能。片上USB3.0交換機是一種高速雙向無源交換機，提供靈活的開關以適應連接器翻轉。該開關還可以處理2-ch數據/ 2-ch視頻和所有4-ch視頻之間的muxing。

有兩個數字音頻輸出接口，I2S和SPDIF。兩者都支持8-ch LPCM或最大192kHz采樣率的壓縮音頻。

該設備能夠通過集成的微處理器實現自動操作，該微處理器使用嵌入式SPI閃存進行固件存儲。通過使用專用配置I2C從接口，還可以進行系統控制。

1. Description

The LT8712EXC is a high performance Type-C/DP1.2 to HDMI2.0/VGA converter, designed to connect a USB Type-C source or a DP1.2 source to a VGA sink and an HDMI2.0 sink simultaneously.

The LT8712EXC integrates a DP1.2 compliant receiver (MST capable), a high-speed triple-channel video DAC and an HDMI2.0 compliant transmitter. Also, two CC controllers are included for CC communication to implement DP Alt Mode and power delivery function, one for upstream Type-C port and another for downstream port. On-chip USB3.0 switch is a high-speed bi-directional passive switch which provides flexible switching to accommodate connector flipping. This switch also handles muxing between 2-ch data / 2-ch video and all 4-ch video.

Two digital audio output interfaces are available, I2S and SPDIF. Both support 8-ch LPCM or compressed audio at maximum 192kHz sample rate.

The device is capable of automatic operation which is enabled by an integrated microprocessor that uses an embedded SPI flash for firmware storage. System control is also available through the use of a dedicated configuration I2C slave interface.
