CREATE AND SAMPLE YOUR CUSTOM ZL40253 HERE
The ZL40253 is a 10-output programmable fanout buffer with multi-format I/O and dividers offers the ability to create multiple copies of a clock signal and distribute them among several loads with minimal additive jitter. The ZL40253 features an intuitive graphical user interface (GUI) and the ability to create factory pre-programmed devices with ease using Microsemi’s web tool, miClockDesigner. These pre-programmed devices—which have pin-selectable configurations at power-up—ensure clock availability and proper system bring-up for all applications.
Additional Features
Four Flexible Input Clocks: one crystal/CMOS input, two differential/CMOS inputs, one single-ended/CMOS input
Any input frequency up to 1GHz (300MHz for CMOS)
Manual clock switching by pin or register
10 Universal Output Clocks with Dividers
Each output has independent divider
Low additive jitter <200fs RMS (12kHz-20MHz, for input frequencies above 100MHz)
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 from GPIO pin or register bit
Per-output skew adjustment
Per-output enable/disable and glitch-less start/stop (stop high or low)
Automatic self-configuration at power-up from external EEPROM; up to 8 configurations pin-selectable
PCIe 1, 2, 3, 4 compliant
Four multi-purpose I/O pins
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/programmi
