NB3W800L
3.3 V 100/133 MHz
Differential 1:8 HCSL-
Compatible Push-Pull Clock
ZDB/Fanout Buffer for PCIe)
Description
The NB3W800L is a low−power 8−output differential buffer that
meets all the performance requirements of the DB800ZL
specification. The NB3W800L is capable of distributing the reference
clocks for Intel® QuickPath Interconnect (Intel QPI), PCIe
Gen1/Gen2/Gen3, SAS, SATA, and Intel Scalable Memory Interconnect
(Intel SMI) applications. A fixed, internal feedback path maintains low
drift for critical QPI applications.
Features
8 Differential Clock Output Pairs @ 0.7 V
Low−power NMOS Push−pull HCSL Compatible Outputs
Cycle−to−cycle Jitter <50 ps
Output−to−output Skew <50 ps
Input−to−output Delay Variation <100 ps
PCIe Gen3 Phase Jitter <1.0 ps RMS
QPI 9.6GT/s 12UI Phase Jitter <0.2 ps RMS
Pseudo−External Fixed Feedback for Lowest Input−to−output Delay
Individual OE Control; Hardware Control of Each Output
PLL Configurable for PLL Mode or Bypass Mode (Fanout
Operation)
100 MHz or 133 MHz PLL Mode Operation; Supports PCIe and QPI
Applications
Selectable PLL Bandwidth; Minimizes Jitter Peaking in Downstream
PLL’s
SMBus Programmable Configurations
Spread Spectrum Compatible; Tracks Input Clock Spreading for Low
EMI
These are Pb−Free Devices
