Microprocessor

The L64733/34 chipset is designed speciﬁcally to meet the needs of

satellite broadcast digital TV and is compliant with the European digital

video broadcast (DVB-S) standard and the technical speciﬁcations for

DSS systems. The chipset forms a complete “L-Band to bits” system.

A typical application of the L64733/34 chipset is satellite digital TV

reception in accordance with ETS 300 421.
