16-Bit Numerically Controlled Oscillator

The Intersil HSP45106 is a high performance 16-bit quadrature Numerically Controlled Oscillator (NCO16). The NCO16 simplifies 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.
