TC358870XBG
Overview
TC358870XBG, Ultra HD to DSI, bridge converts high resolution
(higher than 4 Gbps) HDMI® stream to MIPI® DSI Tx video. It is a
follow up device of TC358779XBG, without scalar functionality. The
HDMI-RX runs at 297 MHz to carry up to 7.2 Gbps video stream. It
requires dual link MIPI DSI Tx, 1 Gbps/data lane, to transmit out a
maximum 7.2 Gbps video data.
P-VFBGA80-0707-0.65-001
Weight: 67 mg (Typ.)
The bridge chip is necessary for current and next generation Application Processors to drive a (dual) DSI
link display by using its HDMI Tx output port.
Features

- EDID Support, Release A, Revision 1 (Feb 9,
2000)
First 128 byte (EDID 1.3 structure)
First E-EDID Extension: 128 bytes of CEA
Extension version 3 (specified in
CEA-861-D)
Embedded 1K-byte SRAM (EDID_SRAM)
Does not support Audio Return Path and HDMI
Ethernet Channels
DSI TX Interface
MIPI DSI compliant (Version 1.1 22 November
2011)
Dual links DSI (DSI0 and DSI1), each link
supports 4 data lanes @1 Gbps/ data lane
- DSI0 carries the left half data of HDMI Rx
video stream and DSI1 carries the right one at
the default configuration.
- Left or right data can be
assigned/programmed to either DSI Tx link
- The maximum length of each half is limited to
2048-pixel plus up to full length overlap, DSI0
data length could be different from that of
DSI1's
- The maximum Hsync skew between DSI0
and DSI1 can be less than 10 ByteClk
Single link DSI, maximum horizontal pixel width
- 2558 pixels (24-bit per pixel)
- 3411 pixels (16-bit per pixel)
Supports video data formats
- RGB666, RGB888, YCbCr444, YCbCr 422
16-bit and YCbCr 422 24-bit
- YCbCr inputs can be converted into RGB
before outputting
I2C Interface
Support for normal (100 kHz), fast mode (400
kHz) and ultrafast mode (2 MHz)
Slave Mode
- To be used by an external Master to configure
all TC358870XBG internal registers, including
EDID_SRAM and panel control
- Support 2 I2C Slave Addresses (0x0F &
0x1F) selected through boot-strap pin (INT)
Audio Output Interface
Up to four I2S data lines for supporting
multi-Channel audio data (5.1 and 7.1)
Maximum audio sample frequency supported is
192 kHz @8 CH
Support 16, 18, 20 or 24-bit data (depend on
HDMI input stream)
Support Master Clock output only
Support 32 bit-wide time-slot only
Output Audio Over Sampling clock (256fs)
