2.General Description
LT87101DC is a signal re-driver with DP or USB3.1 input and Type-C output. DP or USB3.1 signal quality is deeply-optimized and enhanced by performing cable or board trace loss compensation. The device complies with VESA DP1.2 and USB3.1 Gen-1 specifications. It supports 4-lane DP main link interface or 2-lane DP main link plus a USB3.1 Gen-1 interface.The input receiver of LT87101DC features a multi-level programmable linear equalizer, supporting up to 25dB loss compensation due to Inter-Symbol Interference (ISI). The output transmitter re-drives the received signal with multi-level programmable output swing and up to 6dB de-emphasis. A build-in AUX interception
block monitors AUX channel and automatically adjust equalizers and signaling levels in response to DP Link Training Commands. A Low-Frequency Periodic Signal (LFPS) detection, automatic plug and unplug by remote receiver termination sensing and state machine is also integrated for USB3.1 Gen-1 data transfer.
Type-C operating is controlled by CC detect, CC logic and PD management unit. A high performance passive differential switch is also integrated to realize data channel exchange according to Type-C interface insert orientation. This relieves BOM cost and mobile system design complexity. The switch function is compliant with VESA DP Alternate Mode standard and support Pin Assignment C/E or D/F in different applications.
The chip internally integrates an 8-bit OCM and flash memory (stacked die) to configure and run program. Online software upgrade is also supported.
The LT87101DC is fabricated in advanced CMOS process and implemented in a small outline 5mmx5mm QFN40 package. This package is RoHS compliant and specified to operate from -40°C to +85°C.
