8V49NS0412 - NG Clock Generator

General Description

The 8V49NS0412 is a clock generator with four output dividers: three integers, and one that is either integer or fractional.

Key Features

  • Eleven differential LVPECL and LVDS outputs with programmable voltage swings.
  • One LVCMOS output: Input reference can be passed to this output.
  • The clock input operates in full differential mode (LVDS, LVPECL) or single-ended LVCMOS mode.
  • Driven from a crystal or differential clock input.
  • 2.4.
  • 2.5GHz PLL frequency range supports Ethernet, SONET, and CPRI frequency plans.
  • Four Integer output dividers with a range of output divide ratios (see Table 5).

FemtoClock® NG Clock Generator with Four Dividers 8V49NS0412 Datasheet Description The 8V49NS0412 is a clock generator with four output dividers: three integers, and one that is either integer or fractional. When used with an external crystal, the 8V49NS0412 generates high-performance timing for the communications and datacom markets, especially for applications that demand extremely low phase noise, such as 10GE, 40GE, 100G, and 400GE. The 8V49NS0412 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.
