LT86101HC
1. Description

LT86101HC is a TMDS signal re-driver with HDMI1.4b interfaced input and Type-C interfaced output. TMDS signal quality is deeply-optimized and enhanced by performing cable and board trace loss compensation.
The input receiver of LT86101HC features a multi-level programmable linear equalizer, supporting up to 25dB loss compensation due to the Inter-Symbol Interference (ISI). The output transmitter re-drives the received signal with multi-level programmable output swing and maximum 6dB de-emphasis. In coordination with DDC  channel, a build-in frequency detector monitors clock channel and automatically adjust input equalization and output swing.
Type-C operating is controlled by CC detect, CC logic and PD management unit. A high performance passive differential switch compliant with HDMI1.4b Alternate Mode is also integrated to realize clock and data channel exchange according to Type-C interface insert orientation. This relieves BOM cost and mobile system design complexity.
LT86101HC internally integrates an 8-bit OCM and SPI flash memory (stacked die) to configure and run program. Online software upgrade is also supported.
The LT86101HC 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.
