Features
• Two LVPECL output pairs
Each output supports independent frequency selection at 25MHz,
125MHz and 156.25MHz
• One differential input supports the following input types: LVPECL,
LVDS
• Accepts input frequencies 8kHz, 25MHz,125MHz and 155.52MHz
• First stage PLL bandwidth can be optimized for jitter attenuation
and reference tracking using external loop filter connection
• FemtoClock frequency multiplier provides low jitter, high
frequency output
• Absolute pull range: 50ppm
• FemtoClock VCO frequency: 625MHz
• RMS phase jitter @ 25MHz, using a 25MHz crystal
(12kHz – 5MHz): 0.238ps (typical), 0.30ps (maximum)
• RMS phase jitter @ 125MHz, using a 25MHz crystal
(12kHz – 20MHz): 0.223ps (typical), 0.30ps (maximum)
• RMS phase jitter @ 156.25MHz, using a 25MHz crystal
(12kHz – 20MHz): 0.223ps (typical), 0.30ps (maximum)
• 3.3V supply voltage
• -40°C to 85°C ambient operating temperature
• Available in lead-free (RoHS 6) package
