HSP45314 - Intersil Corporation

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 are added modulo 48 bits with the alignment shown in Table 1. .
