General Description
The LT8711EH-C is a high performance Type-C/DP1.2 to
HDMI2.0 converter, designed to connect a USB Type-C
source or a DP1.2 source to an HDMI2.0 sink. The
LT8711EH-C integrates a DP1.2 compliant receiver, 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.
The DP interface comprises 4 main lanes, AUX channel,
and HPD signal. The receiver supports maximum 5.4Gbps
(HBR2) data rate per lane. The DP receiver incorporates
HDCP 1.3 content protection scheme with embedded key
for secure transmission of digital audio-video content.
The HDMI interface includes 4 TMDS clock/data pairs, DDC,
and HPD signal. The HDMI transmitter is capable of
supporting up to 6Gpbs data rate, quite adequate for
handling video resolutions up to FHD 1080p 120Hz 3D and
UHD 4k 60Hz formats. The transmitter performs
downstream RX sensing in both DC and AC coupling
applications. The HDMI transmitter incorporates HDCP
engines which support both HDCP1.4 and HDCP2.2. With
the inclusion of HDCP, the LT8711EH-C allows secure
transmission of protected content. Embedded key is
available that provides the highest level of HDCP key
security.
The DP receiver PHY is HDMI signal compatible. It can
receive HDMI signal and then bypass to the HDMI
transmitter PHY. This feature allows the LT8711EH-C to
ePad and is specified over the -40℃ to +85℃ operating
temperature range.
