描述 Description

CREATE AND SAMPLE YOUR CUSTOM ZL30267 HEREThe 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.

特性 Features

The two APLLs have 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 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 (see ZL30266 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, 5 & 6 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)
