General Description

The NB3W1900L 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 NB3W1900L internal PLL is optimized to support 100 MHz and 133 MHz frequency operation.

The NB3W1900L is developed with the low-power NMOS Push-Pull buffer type.

Key Features

  • 19 Low Power Differential Clock Output Pairs @ 0.7 V.
  • Output-to-Output Skew Performance: < 85 ps.
  • Cycle-to-Cycle Jitter (PLL Mode): < 50ps.
  • Low Phase Jitter (Intel QPI, PCIe Gen 2/Gen 3 Phase Jitter Compliant).
  • Input-to-Output Delay Variation: < 50 ps.
  • Fixed-Feedback for Lowest Input-to-Output Delay Variation.
  • Spread Spectrum Compatible; Tracks Input Clock.
