Wardy has documented his DS1077 configurable oscillator with the Arduino:
I’ve finally had a chance to get around to playing with the DS1077 configurable oscillator!
The circuit to get it working is very simple, just hook up the Ardiono as the I2C master, I used a 10K pullup resistor on both the SCL and SDA lines. I tied CTR0 and CTR1 on the DS1077 to GND to enable the chip all the time.
hi thanks for your input I accidentally bought a ds1077-133 to experience the possibility that it can be used as the local oscillator design programmable radio receiver SDR (Software Defined Radio)
