FN2815.3
16-Bit Numerically Controlled Oscillator
Intersil HSP45106/883 high performance 16-bit quadrature Numerically Controlled Oscillator (NCO16). NCO16 simplifies applications requiring frequency phase agility such frequency-hopped modems, modems, spread spectrum communications, precision signal generators. shown Block Diagram, HSP45106/883 divided into Phase/Frequency Control Section (PFCS) Sine/Cosine Section. inputs Phase/Frequency Control Section consist microprocessor interface individual control lines. frequency resolution bits, which provides resolution better than 0.006Hz 25.6MHz. User programmable center frequency offset frequency registers give user capability perform phase coherent switching between sinusoids different frequencies. Further, programmable phase control register allows phase control better than 0.006o. applications requiring level PSK, three discrete inputs provided simplify implementation. output PFCS 32-bit phase argument which input Sine/Cosine Section conversion into sinusoidal amplitude. outputs Sine/Cosine Section 16-bit quadrature signals. spurious free dynamic range this complex vector greater than 90dBc. added flexibility when using NCO16 conjunction with DAC's, choice either parallel serial outputs with either two's complement offset binary encoding provided. addition, synchronization signal available which signals serial word boundaries.
