Data Sheet
General Description
The 843S1333D is a high frequency clock generator. The 843S1333D uses an external 20MHz crystal to synthesize 1333.33MHz. The 843S1333D has excellent cycle-to-cycle and RMS period jitter performance.
The 843S1333D operates at 3.3V operating supply and is available in a fully RoHS compliant 8-lead TSSOP package.
Features
One differential LVPECL output Crystal oscillator interface designed for 18pF, 20MHz parallel
resonant crystal
Cycle-to-Cycle Jitter: 14ps (maximum) Period Jitter, RMS: 2.6ps (maximum) Output Duty Cycle: 48 – 52% Full 3.3V supply mode 0°C to 70°C ambient operating temperature Available in lead-free (RoHS 6) package
