Description
The 843N252-45 is a 1 LVPECL and 1 LVCMOS output Synthesizer optimized to generate Ethernet reference clock frequencies.
Features
- Fourth generation FemtoClock® Next Generation (NG) technology.
- One differential 3.3V LVPECL output and one LVCMOS/LVTTL
output.
- Crystal oscillator interface designed for a 25MHz parallel resonant
crystal.
- A 25MHz crystal generates output frequencies of: 156.25MHz and
125MHz.
- VCO frequency: 625MHz.
- RMS Phase Jitter @ 156.25MHz, (12kHz.
- 20MHz) using a
25MHz crystal: 0.33ps (typical).
- RMS Phase Jitter @ 125MHz, (12kHz.
