8T49N240 Clock Generator and Jitter Attenuator for 10Gbps and 40/100Gbps Multi-lane Interfaces

An overview of IDT's 8T49N240 programmable clock generator and jitter attenuator IC, featuring sub-200fs phase noise, helping to ease design constraints and lower total system costs 10Gbps and 40/100Gbps multi-lane systems.

The IDT® 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.

The 8T49N240 features a 6 x 6 mm package footprint, requiring considerably less PCB area than most other solutions with this level of performance and flexibility. The device is also suitable for 25/28Gbps interfaces.
