NB3N3011
3.3 V 100 MHz / 106.25 MHz
PureEdge Clock Generator
with LVPECL Differential
Output
Description
The NB3N3011 is a Fibre Channel Clock Generator and uses a
26.5625 MHz crystal to synthesize 106.25 MHz or a 25 MHz crystal
to synthesize 100 MHz. The NB3N3011 has excellent <1 ps phase
jitter performance over the 637 kHz – 10 MHz integration range. The
NB3N3011 is packaged in an 8−Pin 4.4 mm x 3.0 mm TSSOP, making
it ideal for use in systems with limited board space.
Features
• PureEdge Clock Family Provides Accuracy and Precision
• One Differential LVPECL Output
• Crystal Oscillator Interface Designed for Fundamental Mode 18 pF
Parallel Resonant Crystal (25 MHz or 26.5625 MHz)
• Output Frequency: 106.25 MHz (26.5625 MHz Crystal) or 100 MHz
(25 MHz Crystal)
• VCO Range: 760 MHz − 950 MHz
• RMS Phase Jitter @ 100 MHz, using a 25 MHz Crystal
(637 kHz − 10 MHz): 0.29 ps (Typical)
• RMS Phase Noise at 106.25 MHz
Phase noise:
Offset Noise Power
100 Hz −108 dBc/Hz
1 kHz −122 dBc/Hz
10 kHz −135 dBc/Hz
100 kHz −135 dBc/Hz
• 3.3 V Power Supply
• −40°C to 85°C Ambient Operating Temperature
• These are Pb−Free Devices*
