NB3N1900K
3.3V 100/133 MHz
Differential 1:19 HCSL
Clock ZDB/Fanout Buffer for
PCIe[
Description
The NB3N1900K differential clock buffers are designed to work in
conjunction with a PCIe compliant source clock synthesizer to provide
point−to−point clocks to multiple agents. The device is capable of
distributing the reference clocks for Intel® QuickPath Interconnect
(Intel QPI), PCIe Gen1, Gen2, Gen3. The NB3N1900K internal PLL is
optimized to support 100 MHz and 133 MHz frequency operation.
The NB3N1900K supports HCSL output levels.
Features
• Fixed Feedback Path for Lowest Input−to−Output Delay
• Eight Dedicated OE# Pins for Hardware Control of Outputs
• PLL Bypass Configurable for PLL or Fanout Operation
• Selectable PLL Bandwidth
• Spread Spectrum Compatible: Tracks Input Clock Spreading for Low
EMI
• SMBus Programmable Configurations
• 100 MHz and 133 MHz PLL Mode to Meet the Next Generation
PCIe Gen2 / Gen 3 and Intel QPI Phase Jitter
• 2 Tri−Level Addresses Selection (Nine SMBUS Addresses)
• Cycle−to−Cycle Jitter: < 50 ps
• Output−to−Output Skew: < 65 ps
• Input−to−Output Delay: Fixed at 0 ps
• Input−to−Output Delay Variation: < 50 ps
• Phase Jitter: PCIe Gen3 < 1 ps rms
• Phase Jitter: QPI 9.6GB/s < 0.2 ps rms
• QFN 72−pin Package, 10 mm x 10 mm
• These are Pb−Free Devices
