Datasheet
General Description
The 843S1066D is a high frequency clock generator. The
843S1066D uses an external 20MHz crystal to synthesize either
1066.67MHz or 1600MHz. The 843S1066D has excellent
cycle-to-cycle and RMS period jitter performance.
The 843S1066D 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: 12ps (maximum)
• Period Jitter, RMS: 2.8ps (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
• For functional replacement part use 8V97051
