Pin Name	Description
VCC	This is a voltage supply pin. 3.3V or 5V power input
GND	GND Pin.
W_CLK	Frequency Update. On the rising edge of this clock, the DDS will update to the frequency (or phase) loaded in the data input register, it then resets the pointer to Word 0
DATA	D7, Serial Load
RESET	Reset. This is the master reset function; when set high, it clears all registers (except the input register) and the DAC output will go to Cosine 0 after additional clock cycles
D0–D7	8-Bit Data Input. This is the 8-bit data port for iteratively loading the 32-bit frequency and 8-bit phase/28–25 control word. D7 = MSB; D0 = LSB. D7 (Pin 25) also serves as the input pin for the 40-bit serial data word.
Square Wave Output 1	This is the comparator’s true output
Square Wave Output 2	This is the comparator’s complement output.
Sine Wave Output 1	Analog Current Output of the DAC.
Sine Wave Output 2	The Complementary Analog Output of the DAC.
