The miClockSynth ZL30267 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 ZL30267 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.

• 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
• The two APLLs have fractional dividers and integer dividers to make four independent frequency families
• 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 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)
