This product is a high-performance 16-bit quadrature numerically controlled oscillator (NCO16) that simplifies applications requiring frequency and phase agility such as frequency-hopped modems, PSK modems, spread spectrum communications, and precision signal generators.
The Intersil HSP45106/883 is a high-performance 16-bit quadrature Numerically Controlled Oscillator (NCO) designed to simplify applications requiring frequency and phase agility. It is divided into a Phase/Frequency Control Section and a Sine/Cosine Section, supporting features such as 32-bit frequency resolution, programmable center and offset frequencies, and 8-level PSK support via a three-pin interface. The device provides simultaneous 16-bit sine and cosine outputs with a spurious-free dynamic range greater than 90dBc.
