HSP45106 Data Sheet October 1999 File Number 2809.5 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 S
