NB3N551: Clock / Data Fanout Buffer, 1:4, 3.3 V, with CMOS Outputs
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- Input/Output clock frequency up to 180 MHz
- Low Skew Ouptuts (50ps)
- Output Enable puts device in three-state mode
- Operating Range: VDD = 3.0 V to 5.25V
- Full Industrial Temperature Range 8-pin SOIC
- Full RoHS certification
| Benefits- Multiply the low frequency output of inexpensive crystals to the full system frequency
- Minimize timing deviations and synchronization issues
- Creates a high impedance output with no logic low or logic high value
- Ensures operation in the majority of designs
- Small package with robust thermal capability
- Meets all green international materials standards
|
Applications- Clock fan out in routers, switches and other networking applications
