Device Overview

Summary

ZL40253 10-output programmable fanout buffer with multi-format I/O and dividers  offers the ability to create multiple copies of a clock signal and distribute them among several loads with minimal additive jitter.

The ZL40253 features an intuitive graphical user interface (GUI) and the ability to create factory pre-programmed devices with ease using Microsemi’s web tool, miClockDesigner. These pre-programmed devices—which have pin-selectable configurations at power-up—ensure clock availability and proper system bring-up for all applications.

Additional Features
  • Four Flexible Input Clocks: one crystal/CMOS input, two differential/CMOS inputs, one single-ended/CMOS input
  • Any input frequency up to 1GHz (300MHz for CMOS)
  • Manual clock switching by pin or register
  • 10 Universal Output Clocks with Dividers
  • Each output has independent divider
  • Low additive jitter <200fs RMS (12kHz-20MHz, for input frequencies above 100MHz)
  • Each output configurable as LVDS, LVPECL, HCSL, 2xCMOS or HSTL
  • In 2xCMOS mode, the P and N pins can be different frequencies (e.g. 125MHz and 25MHz)
  • Multiple output supply voltage banks with CMOS output voltages from 1.5V to 3.3V
  • Precise output alignment circuitry from GPIO pin or register bit
  • Per-output skew adjustment
  • Per-output enable/disable and glitch-less start/stop (stop high or low)
  • Automatic self-configuration at power-up from external EEPROM; up to 8 configurations pin-selectable
  • PCIe 1, 2, 3, 4 compliant
  • Four multi-purpose I/O pins
  • SPI or I2C processor Interface
  • Core supply voltage options: 2.5V only, 3.3V only, 1.8V+2.5V or 1.8V+3.3V
  • Space-saving 8x8mm QFN56 (0.5mm pitch)
  • Easy-to-use evaluation/programming software
