8V49NS0412 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 munications and data markets, especially for applications that demand extremely low phase noise, such as 10GE, 40GE, 100G, and 400GE.
8V49NS0412 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)
- One Fractional output divider can generate any desired output frequency
- Support of output power-down
- Excellent clock output phase noise
- 143dBc/Hz
