NB3N551: Clock / Data Fanout Buffer, 1:4, 3.3 V, with CMOS Outputs

Product Description
The NB3N551 is a low skew 1-to 4 clock fanout buffer, designed for clock distribution in mind. The NB3N551 specifically guarantees low output-to-output skew. Optimal design, layout and processing minimize skew within a device and from device to device. The output enable (OE) pin three-states the outputs when low.
Features   Benefits
     
  • Input/Output clock frequency up to 180 MHz
 
  • Multiply the low frequency output of inexpensive crystals to the full system frequency
  • Low Skew Ouptuts (50ps)
 
  • Minimize timing deviations and synchronization issues
  • Output Enable puts device in three-state mode
 
  • Creates a high impedance output with no logic low or logic high value
  • Operating Range: VDD = 3.0 V to 5.25V
 
  • Ensures operation in the majority of designs
  • Full Industrial Temperature Range 8-pin SOIC
 
  • Small package with robust thermal capability
  • Full RoHS certification
 
  • Meets all green international materials standards
Applications
  • Clock fan out in routers, switches and other networking applications
