ZL30260,ZL30261,ZL30262,ZL30263
Two Frequency Family High Performance Frequency Synthesizers and Rate Converters
Overview
|
The miClockSynth ZL30260–ZL30263 family of high-performance, any-rate multiplier and frequency synthesizer devices simplifies board design by generating ultra-low-jitter clock signals from a single crystal or crystal oscillator while generating additional independent frequency families. |
ZL30260-ZL30263 Product Brief
White Paper: PCI Express Refclk Jitter Compliance
Applications/Uses
- Clocks for Processors, NPUs, FPGAs, 10G CDRs, high-speed ADCs and DACs, PCIe interface devices, Ethernet switches and PHYs
- Timing generation for optical, storage, networking and broadcast video applications
- OTN, SONET,/SDH, WDM
Key Features
- Two 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
- Glitchless clock switching by pin or register
- 6 or 10 Any-Frequency, Any-Format Outputs
- Any output frequency from 1Hz to 1045MHz
- 2 fractional-N APLLs with 0ppm error
- Each APLL has a fractional divider and an integer divider to make a total of 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
- 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 and per-output phase adjustment
- Per-output enable/disable and glitchless start/stop (stop high or low)
General Features
- Automatic self-configuration at power-up from internal or external EEPROM; up to 8 configurations pin-selectable
- External feedback for zero-delay applications
- Numerically controlled oscillator mode
- Spread-spectrum modulation mode
- 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)
- Easy-to-use evaluation/programming software
- Create factory pre-programmed devices using Microsemi’s web tool, miClockDesigner.
