Device Overview

Summary

The ZL40268 is 3x8 HCSL/LVDS/LVPECL clock fan out buffer with ultra-low additive jitter of 24fs capable of operating at frequencies up to 1.5 GHz. Using the 8 output ZL40268 and utilizing the individual output pins or I2C interface, you can create hot-swappable PCIe clocktrees.

Applications include PCI Express generation 1/2/3/4/5 clock distribution, Intel QPI and UPI distribution, Servers, storage and data centers, switches and routers.

Additional Features
  • 3 to 1 input Multiplexer: Two inputs accept any differential (LVPECL, HCSL, LVDS, SSTL, CML, LVCMOS) or a single ended signal and the third input accepts a crystal or a single ended signal
  • Eight differential HCSL/LVDS/LVPECL outputs
  • Ultra-low additive jitter: 24fs (integration band: 12kHz to 20MHz at 625MHz clock frequency)
  • Supports clock frequencies from 0 to 1.5GHz
  • Supports 2.5V or 3.3V power supplies on HCSL/LVDS/LVPECL outputs
  • Embedded Low Drop Out (LDO) Voltage regulator provides superior Power Supply Noise Rejection
  • Maximum output to output skew of 50ps
  • Device controlled via I2C or hardware control pins
  • Factory configurable default settings via OTP
  • Transparent for spread spectrum clock
  • Applications
    • PCIe Gen1/2/3/4/5 clock distribution
    • Wired communications: OTN, SONET/SDH, GE, 10 GE, FC and 10G FC
    • General purpose clock distribution
