GENERAL DESCRIPTION
The ICS843031 is a 1 Gigabit Ethernet Clock Generator. The
ICS843031 can synthesize 1 Gigabit Ethernet, SONET, or
Serial ATA reference clock frequencies with the appropriate
choice of crystal and output divider. The ICS843031 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
Output frequency range: 290MHz - 350MHz
VCO frequency range: 580MHz - 700MHz
RMS phase jitter @312.5MHz (1.875MHz - 20MHz):
0.475ps (typical)
RMS phase jitter @318.75MHz (1.875MHz - 20MHz):
0.475ps (typical)
3.3V operating supply
0°C to 70°C ambient operating temperature
Available in both standard (RoHS 5) and lead-free (RoHS 6)
