An overview of the IDT® 8T49N240, highly programmable clock generator and jitter attenuator IC. The device features less than 200fs of phase noise, providing valuable system design margin for 10Gbps interfaces in wireline and wireless communication networks. The additional phase noise margin eases system design constraints, allowing engineers to minimize bit error rates (BER) while lowering overall system costs.
The 8T49N240 is the latest member of IDT's third-generation Universal Frequency Translator (UFT™) family. It features the ability to produce virtually any common output frequency from virtually any input frequency. The highly flexible, high-performance clock generator and jitter attenuator is ideal for 10Gbps or multi-lane 40Gpbs / 100Gbps timing applications where 300fs of phase noise is typically the maximum acceptable amount allowed at the physical ports. The 200fs phase noise specification of the 8T49N240 provides ample noise margin, enabling engineers to simplify their clock tree designs and utilize lower cost PCBs.
