843S1066D Datasheet | Renesas

Crystal-to-3.3V LVPECL Frequency Synthesizer 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 Ro HS pliant 8-lead TSSOP package.. Features - One differential LVPECL output - Crystal oscillator interface designed for 18p F, 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 (Ro HS 6) package - For functional replacement part use 8V97051 Table 1.
