Description:

Commlinktm direct digital synthesizer.

HSP45314, CommLinkTM Direct Digital Synthesizer

The HSP45314 is an NCO with an integrated 14-bit DAC designed to run in excess of 125MSPS.

The NCO is a 16-bit output design, which is rounded to 14 bits for input to the DAC.

The frequency control is the sum of a 48-bit center frequency word and a 48-bit offset frequency word.

The two components ar

HSP45314 TM Data Sheet May 2000 File Number 4820.2 CommLinkTM Direct Digital Synthesizer The 14-bit HSP45314 provides a complete Direct Digital Synthesizer (DDS) system in a single 48-pin LQFP package.

A 48-bit Programmable Carrier NCO (numerically controlled oscillator) and a high speed 14-bit DAC (digital to analog converter) are integrated into a stand alone DDS.

The DDS accepts 48-bit center and offset frequency control information via a parallel processor interface.
