These integrated circuits provide global compliance using a singlehardware solution while reducing the PCB footprint and total solution bill-of-materials. Optimized for customer premise equipment (CPE) applications, these best-in-classsolutions address global telecom standards through a high degree of programmability.Additionally, these products are designed using standard digital CMOS. This reducespower and cost while increasing system performance and flexibility through increasedintegration without sacrificing system performance.
