Overview
The TC358774XBG/TC358775XBG Functional Specification defines
operation of the DSI TO LVDS low power chip (or more abbreviated,
TC358775XBG chip). 775XBG is the follow-up chip of TC358764XBG/
TC35865XBG, which:
P-VFBGA49-0505-0.65-001
Weight: 31 mg (Typ.)
1. Is pin compatible to TC358764XBG/TC358765XBG
2. Exhibit LVDS Tx block operates at 1.8V @135 MHz to reduce operation
power
TC358775XBG
3. Update 4-lane DSI Rx max bit rate @ 1 Gbps/lane to support
1920×1200×24 @60fps
4. Add STBY pin with to enable turning on VDDIO power first before other
power supplies.
P-VFBGA64-0606-0.65-001
Weight: 47 mg (Typ.)
The primary function of this chip is DSI-to-LVDS Bridge, enabling video
streaming output over DSI link to drive LVDS-compatible display panels.
The chip supports up to 1600×1200 24-bit pixel resolution for single-link LVDS and up to WUXGA (1920×1200
24-bit pixels) resolution for dual-link LVDS. As a secondary function, the chip also supports an I2C Master which
is controlled by the DSI link; this may be used as an interface to any other control functions through I2C.

by Host through DSI link (multi-master is not
supported)
● LVDS FPD Link Transmitter
Supports single-link or dual-link
Maximum pixel clock frequency of 135 MHz.
Power management features to save power
Maximum pixel clock speed of 135 MHz for single-
link or 270 MHz for dual-link
Configuration registers is also accessible through
I2C Slave interface
