This is a breakout board for the dual-output, programmable oscillator DS1077. It also contains filter capacitor.

The DS1077 can be used to generate a wide range frequencies from the kHz range up to 133MHz. Depending on the amount of control needed, it can operate stand-alone, or processor-controlled using the 2-wire interface (I2C)

The DS1077 can be used as a processor-controlled frequency synthesizer or as a standalone oscillator. The two synchronous output operating frequencies are user-adjustable in multiples of the master frequency.

The specific output frequencies chosen are stored in non-volatile (EEPROM) memory. The DS1077 defaults to these values upon power-up.

The DS1077 features a 2-wire serial interface that allows in-circuit on-the-fly programming.  Design changes can be accommodated in-circuit on-the-fly by simply programming different values into the device (or reprogramming previously programmed devices).
