10-Output Clock Generator int. EEPROM

Key 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 < 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 (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)

Description

[CREATE AND SAMPLE YOUR CUSTOM ZL30267 HERE](https://clockworks.microchip.com/microchip/design/inputZL) 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.
