8T49NS010

Clock Synthesizer and Fanout Buffer/Divider 8T49NS010 DATA SHEET General Description The 8T49NS010 is a Clock Synthesizer and Fanout Buffer/Divider. When used with an external crystal, the 8T49NS010 generates high performance timing geared towards the communications and datacom markets, especially for applications demanding extremely low phase noise jitter, such as 10, 40 and 100GE. The 8T49NS010 provides versatile frequency configurations and output formats and is optimized to deliver excellent phase noise performance. The device delivers an optimum combination of high clock frequency and low phase noise performance, combined with high power supply noise rejection. The 8T49NS010 supports two types of output levels. FORMAT #1 Outputs provide an output level with 750mV typical swing, and requires external DC termination. FORMAT #2 Outputs provide a similar swing level which does not require DC termination. The device can be configured through an I2C serial interface and is offered in a lead-free (RoHS6) 56-pin VFQFN package. The extended temperature range supports telecommunication and networking end equipment requirements. Features Ten differential outputs The input operates in full differential mode (LVDS, LVPECL) or single-ended LVCMOS mode Can be driven from a crystal or differential clock Support of output power-down Excellent clock output phase noise Offset Output Frequency Single-side Band Phase Noise 100kHz 156.25MHz -144 dBc/Hz Phase Noise RM...
