FEATURES
• Two LVPECL outputs
Each output supports independent frequency selection at
25MHz, 125MHz, 156.25MHz and 312.5MHz
• Two differential inputs support the following input types: LVPECL,
LVDS, LVHSTL, SSTL, HCSL
• Accepts input frequencies from 8kHz to 155.52MHz including
8kHz, 1.544MHz, 2.048MHz, 19.44MHz, 25MHz, 77.76MHz,
125MHz and 155.52MHz
• Attenuates the phase jitter of the input clock by using a lowcost
pullable fundamental mode VCXO crystal
• VCXO PLL bandwidth can be optimized for jitter attenuation
and reference tracking using external loop fi lter connection
• FemtoClock frequency multiplier provides low jitter, high frequency
output
• Absolute pull range: 50ppm
• FemtoClock VCO frequency: 625MHz
• RMS phase jitter @ 125MHz, using a 25MHz crystal
(10kHz – 20MHz): 1.3ps (maximum)
• 3.3V supply voltage
• -40°C to 85°C ambient operating temperature
• Available in lead-free (RoHS 6) package
• For functional replacement device use 813N252CKI-02LF
