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.
