Serializers, Deserializers FAQ

How many NJU3730 devices can operate on a single I2C bus?

Up to three NJU3730 devices can be connected to the same I2C bus, distinguished by their selectable slave addresses.

What determines the slave address of the NJU3730?

The slave address is determined by the logic state of the SEL terminal: Low Level, Open, or High Level correspond to different predefined addresses.

What is the maximum clock frequency supported by the I2C interface?

The maximum clock frequency (fSCL) supported by the I2C interface is 100 kHz.
