I was under the impression that the cpu did the workload ?http://www.elektor.com/news/Tiny-hybrid-TV-Tuner/It's not like I'm going to connect this via i2c on my Arduino now is it? (But I guess I could control it via an Arduino)
It looks like the IC takes RF in, does all the tuning, signal extraction, ADC, and then puts the data out on a differential pair, LIF_P and LIF_N. I am going to make a cautious guess that the that data rate is going to be too damn high for the Arduino to handle.
I2c is probably for the control or configuration registers
