SI5320 - SONET/SDH PRECISION CLOCK MULTIPLIER IC

General Description

The Si5320 is a precision clock multiplier designed to exceed the requirements of high-speed communication systems, including OC-192/OC-48 and 10 GbE.

Key Features

  • Ultra-low-jitter clock output with jitter generation as low as 0.3 psRMS.
  • No external components (other than a resistor and standard bypassing).
  • Input clock ranges at 19, 39, 78, 155, 311, and 622 MHz.
  • Output clock ranges at 19, 155, or 622 MHz.
  • Digital hold for loss of input clock.
  • Support for forward and reverse FEC clock scaling.
  • Selectable loop bandwidth.
  • Loss-of-signal alarm output.
  • Low power.
  • Small size (9x9 mm).
