ICS843S1333D Datasheet, PDF (1/14 Pages) Integrated Device Technology – One differential LVPECL output

Crystal-to-3.3V LVPECL Clock Synthesizer ICS843S1333D
DATA SHEET
General Description
ICS
HiPerClockS™
The ICS843S1333D is a high frequency clock
generator. The ICS843S1333D uses an external
20MHz crystal to synthesize 1333.33MHz. The
ICS843S1333D has excellent cycle-to-cycle and RMS
period jitter performance.
The ICS843S1333D operates at 3.3V operating supply and is
available in a fully RoHS compliant 8-lead TSSOP package.
