16-Bit Numerically Controlled Oscillator

Features

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 Section.

• 25.6MHz, 33MHz Versions

• 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

• <0.008Hz Tuning Resolution at 33MHz

• 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 0.008Hz at 33MHz. User

• Spurious Frequency Components <-90dBc

• 16-Bit Microprocessor Compatible Control Interface

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

Applications

• Direct Digital Synthesis

allows for phase control of better than 0.006 . In applications

requiring up to 8-level PSK, three discrete inputs are

provided to simplify implementation.

• Quadrature Signal Generation

• Spread Spectrum Communications

• PSK Modems

The output of the PFCS is a 28-bit phase 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.

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

• Frequency Hopping Communications

• Precision Signal Generation

For added ﬂexibility when using the NCO16 in conjunction

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

either two’s complement or offset binary encoding is

provided. In addition, a synchronization signal is available

which indicates serial word boundaries.
