Overview
TC358767AXBG
TC358767AXBG is a bridge device that enables video streaming from
a Host (application or baseband processor) over MIPI® DSI or DPI link
to drive DisplayPortTM display panels. TC358767AXBG also supports
audio streaming from the host via I2S interface to the Display panels.
TC358767AXBG provides a low power bridge solution to efficiently
translate MIPI® DSI or DPI transfers to DisplayPortTM transfers. As the
P-VFBGA81-0505-0.50-001
Weight: 47mg (Typ.)
DisplayPortTM uses fewer wires compared to other existing display panel standards, it simplifies the LCD
connectivity. The effect of using TC358767AXBG is to enable existing baseband devices supporting DSI or
DPI streaming to connect to new panels supporting DisplayPortTM interface and also to connect to existing
panels over longer distance using DisplayPortTM adaptors at far-end. TC358767AXBG can interface to up to
two independent devices.
Features

TC358767AXBG
Supports Audio related Secondary Data
Packets.
AUX channel supported at 1 Mbps.
HPD support through GPIO[0] based interrupts
Enhanced mode supported for content
protection.
Support HDCP encryption Version 1.3 with
DisplayPortTM amendment Revision 1.1.
Secure ASSR (Alternate Scrambler Seed
Reset) support for eDP panels
- System designer connects ASSR_DisablePad
to VSS to enable eDP panels and ASSR
- Drive ASSR_DisablePad with an inner ring
VDDS for using DP panels and disable ASSR
- System software read Revision ID field,
0x0500[7:0]:
0x01 indicates eDP panels are used, DPCD
register bit 0x0010A[0] of eDP panel should
be set
0x03 assumes DP panels are connected,
DPCD register bit 0x0010A[0] of DP panel
should Not be set
Stream Policy Maker is assumed handled by the
Host (software/firmware).
- Start Link training in response to HPD & read
final Link training status
- Configure DP link for actual video streaming &
start video streaming
Link Policy maker is assumed shared between
the Host and TC358767AXBG chip.
- In auto_correction = 0 mode, control link
training
- Initiate Display device capabilities read and
configure TC358767AXBG accordingly.
Video timing generation as per panel

link to interface to single DisplayPortTM display
device. Video stream source is from MIPI® DSI

DisplayPortTM Tx as single 2-lane DisplayPortTM
link to interface to single DisplayPortTM display
device. Video stream source is from MIPI® DPI
Host.
MODE S2P: TC358767A uses only Parallel
