The SP5512 is a single-chip frequency synthesiser designed for TV tuning systems. Control data is entered in the standard I2C BUS format. The device has six controllable open-collector output ports (P2-P7), each capable of sinking 20mA. In addition, P6 is a 3-bit 5-level ADC input. The information on these ports can be read via the I2C BUS.

The device has one fixed I2C BUS address and three programmable addresses, allowing two or more synthesisers to be used in a system.
