9DBL0453 - 4-output 3.3V LP-HCSL Zero-Delay Buffer

Download the 9DBL0453 datasheet PDF. This datasheet also covers the 9DBL0443 variant, as both devices belong to the same 4-output 3.3v lp-hcsl zero-delay buffer family and are provided as variant models within a single manufacturer datasheet.

General Description

The 9DBL04x3 devices are 3.3V members of IDT's Full-Featured PCIe clock family.

They support PCIe Gen1-4 Common Clock (CC) architectures and also support NVLINK applications.

The 9DBL04x3 parts have a Loss of Signal (LOS) indicator to support fault-tolerant, high reliability systems.

Key Features

  • Loss Of Signal (LOS) open drain output.
  • 4.
  • 1-200 MHz Low-Power (LP) HCSL DIF pairs.
  • 9DBL0443 default Zout = 100Ω.
  • 9DBL0453 default Zout = 85Ω.
  • Easy AC-coupling to other logic families, see IDT.
