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.
