106.25MHZ, LVCMOS, LVPECL
DUAL OUTPUT OSCILLATOR
GENERAL DESCRIPTION
The ICS843-106 is a Fibre Channel Dual
ICS
Output Oscillator and a member of the
HiPerClockS™ _HiPerClocksTM _{family of high perfor mance}
devices from ICS. The ICS843-106 uses a
25MHz crystal to synthesize 106.25MHz.
The ICS843-106 has excellent jitter performance. The
ICS843-106 is packaged in a small 8-pin TSSOP,
making it ideal for use in systems with limited board space.
FEATURES
• One LVCMOS/LVTTL output, 15Ω output impedance
One LVPECL output pair
• Crystal oscillator interface designed for 25MHz,
18pF parallel resonant crystal
• Output frequency: 106.25MHz
• Random jitter: 3ps (typical)
• Deterministic jitter: 0.24ps (typical)
• 3.3V operating supply
• 0°C to 70°C ambient operating temperature
• Available in both standard and lead-free RoHS-compliant
packages
