LT8711X-B
1. General Description
The LT8711X is a DisplayPort(DP) to VGA converter, designed to connect a DisplayPort source to a VGA sink. The LT8711X integrates a DisplayPort 1.2 compliant receiver, and a high-speed triple-channel video DAC. The receiver port integrates a CC controller which enables DisplayPort Alternate Mode support when connected to a USB Type-C source.
The DisplayPort interface comprises 4 main lanes, AUX channel, and HPD signal. The receiver supports maximum 5.4Gbps (HBR2) data rate per lane and features multi-stream transporting (MST). The high speed differential pairs can be swapped so that the pin order of lane 0 to lane 3 can be flipped. The DisplayPort receiver incorporates HDCP 1.3 content protection scheme with an embedded key option for secure transmission of digital audio-video content.
Two package types are available, LT8711X-A and LT8711X-B, and both are provided in a 64-lead QFN package with ePad and specified over -40℃ to +85℃ operating temperature range.
