16-Bit Numerically Controlled OscillatorThe Intersil HSP45106 is a high performance 16-bit quadrature Numerically Controlled Oscillator NCO16 . The NCO16 simplies applications requiring frequency and phase agility such as frequency-hopped modems, PSK modems, spread spectrum communications, and precision signal generators. As shown in the block diagram, the HSP45106 is divided into a Phase/Frequency Control Section PFCS and a Sine/Cosine Section.The inputs to the Phase/Frequency Control Section consist of a microprocessor interface and individual control lines. The frequency resolution is 32 bits, which provides for resolution of better than 0.008Hz at 33MHz. User programmable center frequency and offset frequency registers give the user the capability to perform phase coherent switching between two sinusoids of different frequencies. Further, a programmable phase control registerallows for phase control of better than 0.006o. In applications requiring up to 8-level PSK, three discrete inputs are provided to simplify implementation.
