8V49NS0312 Description
The 8V49NS0312 is a Clock Generator with four output dividers: three integer and one that is either integer or fractional. When used with an external crystal, the 8V49NS0312 generates high-performance timing geared towards the munications and data markets, especially for applications that demand extremely low phase noise, such as 10, 40, and 100GE.
8V49NS0312 Key Features
- Eleven differential LVPECL, LVDS outputs with programmable voltage swings
- One LVCMOS output
- Input reference maybe bypassed 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 7)
- One Fractional Output divider can generate any desired output frequency
- Support of output power-down
- Excellent clock output phase noise Offset Output Frequency Single-side Band Phase Noise
