SERIAL COMMUNICATION FORMAT

The following diagram shows the PT6961 serial communication format. The DOUT Pin is an N-channel, open-drain

output pin; therefore, it is highly recommended that an external pull-up resistor (1 KΩ to 10 KΩ) must be connected to

DOUT.

RECEPTION (DATA/COMMAND WRITE)

TRANSMISSION (DATA READ)

where: twait (waiting time) ≥ 1µs

It must be noted that when the data is read, the waiting time (twait) between the rising of the eighth clock that has set the

command and the falling of the first clock that has read the data is greater or equal to 1µs.
