ZL30266LDG1 General Description

The miClockSynth ZL30266 high-performance, any-rate multiplier and clock generator simplifies board design by generating ultra-low-jitter clock signals from a single crystal or crystal oscillator while generating additional independent frequency families.

With up to four independent frequency families on one chip, best-in-class jitter performance, and two fractional-N APLLs with both a fractional and integer divider, the ZL30266 creates a complete clock-tree, improving design reliability, reducing bill of materials (BOM) cost, and simplifying design by replacing multiple crystals and peripheral timing components.

Key Features

  • Two APLLs with fractional dividers and integer dividers to make four independent frequency families
  • Four Flexible Input Clocks: One crystal/CMOS input, Two differential/CMOS inputs, One single-ended/CMOS input
  • Any input frequency from 9.72MHz to 1.25GHz (300MHz max for CMOS)
  • Activity monitors, automatic or manual switching
  • Glitch-less clock switching by pin or register
  • 10 Any-Frequency, Any-Format Outputs
  • Any output frequency from 1Hz to 1045MHz
  • High-resolution frac-N APLL with 0ppm error
  • Output jitter from integer multiply and dividers as low as 0.17ps RMS (12kHz-20MHz)
  • Output jitter from fractional dividers is typically < 1ps RMS, many frequencies <0.5ps RMS
  • Each output has an independent divider and is 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 and per-output phase adjustment
  • Per-output enable/disable and glitch-less start/stop (stop high or low)
  • Automatic self-configuration at power-up from external EEPROM (see ZL30267 for internal EEPROM); up to 8 configurations pin-selectable
  • External feedback for zero-delay applications
  • Numerically controlled oscillator mode
  • Spread-spectrum modulation mode
  • Generates PCIe 1, 2, 3, 4 compliant clocks
  • Easy-to-configure design requires no external VCXO or loop filter components
  • 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)
