ZL4026x PCIe® Clock Trees

Microchip's hot-swappable clock trees feature individual output-enabled buffers

Image of Microchip's ZL4026x PCIe Clock TreeMicrochip's ZL4026x family is made up of high-performance, ultra-low jitter, and low-power PCIe® Gen 1 to 5, Intel QPI fan-out buffers with individual output enable pins. Using the 2-output ZL40262 or the 4-output ZL40264 and utilizing the individual output pin, users can create hot-swappable PCIe clock trees. The rich feature-set of the ZL4026x devices make them suitable for a range of applications including PCI Express generation 1/2/3/4/5 clock distribution, Intel QPI and UPI distribution, servers, storage and data centers, switches, and test equipment.

Features
  • One differential input which accepts any differential format
  • Two differential HCSL outputs
  • Ultra-low additive jitter: 24 fs (in 12 kHz to 20 Mhz integration band at 100 MHz clock frequency)
  • Supports clock frequencies from 0 MHz to 400 MHz
  • Supports 2.5 V to 3.3 V power supplies for HCSL outputs
  • Embedded low drop-out (LDO) voltage regulator provides superior power supply noise rejection
  • Max output to output skew of 40 ps
  • Individual output enable pin for each differential pair
  • Transparent for spread-spectrum clock
Applications
  • PCI Express generation 1/2/3/4/5 clock distribution
  • Intel API and Intel UPI clock distribution
  • Low jitter clock trees
  • Logic translation
  • Clock and data signal restoration
  • High performance microprocessor clock distribution
  • Test equipment
