TDO: JTAG Test Data Output
This pin output the serial data of the JTAG Test. The data on TDO is clocked out of the device on the fall-
ing edges of TCK. TDO is a high-Z output signal. It is active only when scanning of data is out. This pin
should be left float when unused.
TDI: JTAG Test Data Input
This pin input the serial data of the JTAG Test. The data on TDI is clocked into the device on the rising
edges of TCK. This pin has an internal pull-up resistor and it can be left disconnected.
3.3 V I/O Power Supply
I/O GND
3.3 V/5 V Power Supply for Transmitter Driver
All VDDT pins must be connected to 3.3 V or all VDDT must be connected to 5 V. It is not allowed to leave
any of the VDDT pins open (not-connected) even if the channel is not used.
For T1 applications, only 5 V VDDT is supported.
