L2340 - Digital Synthesizer

Datasheet Summary

Description

The L2340 is a digital synthesizer that performs waveform synthesis, modulation, and demodulation.

The L2340 automatically generates quadrature matched pairs of 16-bit sine and cosine waves in DACcompatible 16-bit offset binary format with15-bit amplitude and 32-bit phase inputs.

Features

L2340 DEVICES INCORPORATED Digital Synthesizer L2340 DEVICES INCORPORATED Digital Synthesizer DESCRIPTION The L2340 is a digital synthesizer that performs waveform synthesis, modulation, and demodulation. The L2340 automatically generates quadrature matched pairs of 16-bit sine and cosine waves in DACcompatible 16-bit offset binary format with15-bit amplitude and 32-bit phase inputs. Output waveforms can be phase or frequency modulated. Digital output frequencies are restricted to the Nyquist limit. Functional Description The L2340 converts Polar (Phase and Magnitude) data into Rectangular (Cartesian) coordinates. The user selects the numeric format. A valid transformed result is seen at the output after 22 clock cycles and will continue upon every clock cycle thereafter.
