1. About This MegaCore Function
This document describes the Altera ? NCO MegaCore ? function. The Altera NCO
MegaCore function generates numerically controlled oscillators (NCOs) customized
for Altera devices.
You can use the IP Toolbench interface to implement a variety of NCO architectures,
including ROM-based, CORDIC-based, and multiplier-based. IP Toolbench also
includes time and frequency domain graphs that dynamically display the
functionality of the NCO, based on your parameter settings.
A numerically controlled oscillator synthesizes a discrete-time, discrete-valued
representation of a sinusoidal waveform. Designers typically use NCOs in
communication systems. In such systems, they are used as quadrature carrier
generators in I-Q mixers, in which baseband data is modulated onto the orthogonal
carriers in one of a variety of ways.
Figure 1–1 shows an NCO used in a simple modulator system.

Designers also use NCOs in all-digital phase-locked-loops for carrier synchronization
in communications receivers, or as standalone frequency shift keying (FSK) or phase
shift keying (PSK) modulators. In these applications, the phase or the frequency of the
output waveform varies directly according to an input data stream.
