Device Overview

Summary

The ZL30251 is a flexible, high-performance, clock multiplier/generator. From any input clock frequency 9.72MHz to 1250MHz this device can produce frequency-locked output frequencies from 1Hz to 1035MHz and as many as 3 differential or 6 CMOS output clock signals. The ZL30251 has output jitter of 160fs RMS (12kHz to 20MHz). Automatic self-configuration from internal EEPROM allows clock signals to be available immediately after power-up or reset.


Additional Features
  • Four Input Clocks: One crystal/CMOS input, Two differential/CMOS inputs, One single-ended/CMOS input
  • Any input frequency from 9.72MHz to 1250MHz (9.72MHz to 300MHz for CMOS)
  • Clock selection by pin or register control
  • Low-Jitter Fractional-N APLL and 3 Outputs
  • Any output frequency from <1Hz to 1035MHz
  • High-resolution fractional frequency conversion with 0ppm error
  • Easy-to-configure, encapsulated design requires no external VCXO or loop filter components
  • Each output has independent dividers
  • Output jitter as low as 0.16ps RMS (12kHz-20MHz integration band)
  • Outputs are CML or 2xCMOS, can interface to LVDS, LVPECL, HSTL, SSTL and HCSL
  • In 2xCMOS mode, the P and N pins can be different frequencies (e.g. 125MHz and 25MHz)
  • Per-output supply pin 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 four configs, pin-selectable
  • SPI or I2C processor Interface
  • Numerically controlled oscillator mode
  • Spread-spectrum modulation mode
