Renesas Electronics 8V4xNS0x12 FemtoClock® Clock Generators

Renesas Electronics 8V4xNS0x12 FemtoClock® Clock Generators feature 12 outputs in four banks with individual dividers. These clock generators offer three integer output dividers and a fractional output divider. The 8V4xNS0x12 clock generators deliver high-performance timing for the communications and datacom market, especially for applications that demand extremely low phase noise. These clock generators support Ethernet, Synchronous Optical Networking (SONET), and Common Public Radio Interface (CPRI) frequencies up to 2500MHz. The 8V4xNS0x12 clock generators eliminate the need for individual clock domains and fanout buffers, reducing the Bill Of Materials (BOM) and streamlining design.
