16-Bit Numerically Controlled Oscillator

Features

The Intersil HSP45106/883 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

HSP45106/883 is divided into a Phase/Frequency Control

Section (PFCS) and a Sine/Cosine Section.

• This Circuit is Processed in Accordance to MIL-STD-883

and is Fully Conformant Under the Provisions of

Paragraph 1.2.1.

• 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

• <0.006Hz Tuning Resolution at 25.6MHz

• Serial or Parallel Outputs

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.

• Spurious Frequency Components < -90dBc

• 16-Bit Microprocessor Compatible Control Interface

Applications

• Direct Digital Synthesis

The output of the PFCS is a 32-bit phase argument which is

input to the Sine/Cosine Section for conversion into

sinusoidal amplitude. The outputs of the Sine/Cosine

Section are two 16-bit quadrature signals. The spurious free

dynamic range of this complex vector is greater than 90dBc.

• Quadrature Signal Generation

• Modulation - FM, FSK, PSK (BPSK, QPSK, 8PSK)

• Precision Signal Generation

For added flexibility when using the NCO16 in conjunction

with DAC’s, a choice of either parallel of serial outputs with

either two’s complement or offset binary encoding is

provided. In addition, a synchronization signal is available

which signals serial word boundaries.
