DVB-Satellite modulator

Product code: CMS0035

The CMS0035 satellite modulator core is an integrated core featuring our DVB-S/-DSNG modulator(CMS0010) and DVB-S2/-S2X modulator(CMS0025) cores. Thus, our CMS0035 core provides all the functionality required to address the requirements of the ETSI DVB-S forward-link satellite Standard (EN300421), the ETSI DVB-DSNG digital satellite news gathering Standard (EN301210) and also the ETSI DVB-S2 / DVB-S2X forward-link satellite Standard (EN302307-1 and EN302307-2), with optional DVB-S2X VLSNR support.
Modes that are not required may be removed with synthesis options to generate a compact, efficient design.
