The LT8712 is a DisplayPort(DP) to HDMI and VGA converter, designed to connect a DP source to a VGA sink and up to two HDMI sinks simultaneously. The LT8712 integrates a DP 1.2 compliant receiver, a high-speed triple-channel video DAC and two HDMI 1.4 compliant transmitters (transmitter 0 and transmitter 1). The receiver port integrates a CC controller which enables DP Alternate Mode support when connected to a USB Type-C source.
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 that is enabled by an integrated MCU that uses an embedded SPI flash for microcode. System control is also available through the use of a dedicated configuration I2C slave interface.
The LT8712 is provided in two package types, LT8712 and LT8712B. LT8712 is a 128-lead LQFP package with ePad and LT8712B is a 144-ball LFBGA package. Both are specified over -40℃ to +85℃ operating temperature range.
