HSP45106/883 HSP45106/883 TM Data Sheet May 1999 FN2815 FN2815.3 16-Bit Numerically Controlled Oscillator Features The Intersil HSP45106/883 HSP45106/883 is a high performance 16-bit quadrature Numerically Controlled Oscillator (NCO16 NCO16). The NCO16 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 HSP45106/883 HSP45106/883 is divided into a Phase/Frequency Control Section (PFCS) and a Sine/Cosine Section. · This Circuit is Processed in Accordance to MIL-STD-883 MIL-STD-883 and is Fully Conformant Under the Provisions of Paragraph 1.2.1. 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 0.006Hz at 25.6MHz. 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 register allows for phase control of better than 0.006o. In applications requiring up to 8 level PSK, three discrete inputs are provided to simplify implementation. · 25.6MHz Clock Rate · 32-Bit Center and Offset Frequency Control · 16-Bit Phase Control · 8 Level PSK Supported Through Three Pin Interface · Simultaneous 16-Bit Sine and Cosine Outputs · Output in Two's Complement or Offset Binary ·
