TC358840XBG
Overview
TC358840XBG, Ultra HD to CSI-2, bridge converts high resolution
(higher than 4 Gbps) HDMI® stream to MIPI® CSI-2 Tx video. It is a
follow up device of TC358743XBG. The HDMI-RX runs at 297 MHz to
carry up to 7.2 Gbps video stream. It requires dual link MIPI CSI-2 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 which have been designed without video
stream input port except CSI-2 Rx.
Features
● HDMI-RX Interface
video stream and CSI1 carries the right one at
the default configuration.
- Left or right data can be
assigned/programmed to either CSI-2 Tx link
- The maximum length of each half is limited to
2048-pixel, CSI0 data length could be
different from that of CSI1's
HDMI 1.4b

and CSI1 can be less than 10 ByteClk
Single link CSI-2, maximum horizontal pixel
width
- 2558 pixels (24-bit per pixel)
- 3411 pixels (16-bit per pixel)
HDMI InfoFrame data can be transmit over MIPI
CSI-2 at the beginning of each frame (after FS
short packet)
- Color Conversion
4:2:2 to 4:4:4 is supported
4:4:4: to 4:2:2 is supported
RGB888 to YCbCr (4:4:4 / 4:2:2) is
supported
YCbCr (4:4:4 / 4:2:2) to RGB888/666 is
supported
Note: for RGB666 (R=R[5:0],2'b00,
G=G[5:0],2'b00, B=G[5:0],2'b00)
- Maximum HDMI clock speed: 297 MHz
- Audio Supports
Internal Audio PLL to track N/CTS value
transmitted by the ACR packet.
- 3D Support

- RGB666, RGB888, YCbCr444, YCbCr 422
24-bit and YCbCr 422 16-bit
- YCbCr inputs can be converted into RGB
before outputting and vice versa.
- Support HDCP1.4 decryptions (optional)

2000)
First 128 byte (EDID 1.3 structure)
First E-EDID Extension: 128 bytes of CEA
Extension version 3 (specified in
CEA-861-D)
● 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 TC358840XBG internal registers, including
EDID_SRAM and panel control
Embedded 1K-byte SRAM (EDID_SRAM)
Does not support Audio Return Path and HDMI
Ethernet Channels
- Support 2 I2C Slave Addresses (0x0F &
0x1F) selected through boot-strap pin (INT)
● CSI-2 TX Interface (This function is supported
only by TC358840XBG )
● Audio Output Interface
MIPI CSI-2 compliant (Version 1.01 Revision
0.04 – 2 April 2009)
Dual links CSI-2 (CSI0 and CSI1), each link
supports 4 data lanes @ 1 Gbps/data lane
- CSI0 carries the left half data of HDMI Rx
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
