简介

The 9QXL2000B is a 20-output very-low-additive phase jitter fanout buffer for PCIe Gen4 and Gen5. It offers integrated terminations for 85Ω transmission lines with individual output impedance trim and via SMBus registers.
 

特性

  • Low-Power HCSL (LP-HCSL) 85Ω outputs eliminate 80 resistors, saving 130mm2 of area
  • Low-Power HCSL (LP-HCSL) outputs reduce device power consumption by 50%
  • 8 OE# pins configurable to control up to 20 outputs
  • 9 selectable SMBus addresses
  • Spread spectrum compatible
  • 10 × 10 mm 72-VFQFPN package

PCIe Gen5 Clock Buffers

Introducing Renesas’ enhanced PCIe clock buffer family. These PCIe Gen5 clock buffers offer fanout and zero-delay operating modes, supporting both legacy systems and the most complex timing trees within a single device. Unlike many existing solutions, whose performance limitations force their use in fanout buffer mode, these clock buffers meet both PCIe Gen5 and prominent CPU-specific phase jitter requirements in all operating modes. The extremely low 50fs rms PCIe Gen5 additive phase jitter enables multi-level cascading within the strict PCIe Gen5 jitter budget. Renesas’ high-performance oscillators and clock generators provide an ideal clock source for the enhanced PCIe clock buffer family.
