THCV226_16 Datasheet, PDF (22/27 Pages) THine Electronics, Inc. – THCV226 is designed to support video data transmission between the host and display.

Note
1) LVDS Output Pin Connection
In case that the LVDS Rx of destination device is equipped with pull-up resistors connected to higher than
THCV226’s VDD voltage, this can cause violation of absolute maximum ratings to THCV226. This
phenomenon may be happened at power-on phase and Hi-Z state of the whole system including LVDS Rx
device.
One solution for this problem is power-down control for LVDS Rx device during no LVDS input or Hi-Z state
period, if its pull-up resistors can be cut off at power-down state. Another solution is to set THCV226’s OPF
option pin to VDD. This setting provides low fixed data output mode at PDN=1, not Hi-Z state mode.

2) Cable Connection and Disconnection
Do not connect and disconnect the LVDS and CML cables, when the power is supplied to the system.
3) GND Connection
Connect the each GND of the PCB which Transmitter and Receiver. It is better for EMI reduction to place
GND cables as close to LVDS and CML cables as possible.
4) Multi-drop Connect
Multi-drop connect is not recommended.
