SI570 Datasheet Any-rate I2c Programmable Xo/vcxo

Manufacturer: Silicon Laboratories

Overview: Si570/Si571 1 0 M H Z TO 1 . 4 G H Z I 2C P ROGRAMMABLE X O / V C X.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The Si570 XO/Si571 VCXO utilizes Silicon Laboratories’ advanced DSPLL® circuitry to provide a low-jitter clock at any frequency.

The Si570/Si571 are userprogrammable to any output frequency from 10 to 945 MHz and select frequencies to 1400 MHz with <1 ppb resolution.

The device is programmed via an I2C serial interface.

Key Features

  • Any programmable output.
  • Internal fixed crystal frequency frequencies from 10 to 945 MHz and ensures high reliability and low select frequencies to 1.4 GHz aging.
  • I2C serial interface.
  • Available LVPECL, CMOS,.
  • 3rd generation DSPLL® with superior LVDS, and CML outputs jitter performance.
  • 3x better frequency stability than SAW-based oscillators.
  • Industry-standard 5x7 mm package.
  • Pb-free/RoHS-compliant.
  • 1.8, 2.5, or 3.3 V supply.
