The I²C interface runs at 25 MHz.
This order code carries an Active lifecycle status. There is no last-time-buy notice or end-of-life risk on this order code, so it can be specified into production builds without worrying about a forced redesign.
Programming is done by writing to the device's control registers over the I²C bus at up to 25 MHz. Each output channel has an independent PWM brightness register; a single I²C write can update all eight channels simultaneously. The datasheet provides the register map and the sequence for configuring output state, dimming, and group dimming modes.
