FemtoClock Crystal-to-3.3V LVPECL
Clock Generator
ICS843051
General Description
The ICS843051 is a Gigabit Ethernet Clock Generator. The
ICS843051can synthesize 10 Gigabit Ethernet, SONET, or Serial
ATA reference clock frequencies with the appropriate choice of
crystal and output divider. The ICS843051 has excellent phase jitter
performance and is packaged in a small 8-pin TSSOP, making it
ideal for use in systems with limited board space.
Features
One differential 3.3V LVPECL output
Crystal oscillator interface designed for 18pF parallel resonant
crystals
RMS phase jitter at:
155.52MHz (12kHz – 20MHz): 0.74ps (typical)
156.25MHz (1.875MHz – 20MHz): 0.43ps (typical)
161.13MHz (1.933Hz – 20MHz): 0.43ps (typical)
