Features
• Fourth generation FemtoClock® NG technology
• Two single-ended LVCMOS/LVTTL 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, HCSL
• Accepts input frequencies from 8kHz to 155.52MHz including
8kHz, 1.544MHz, 2.048MHz, 19.44MHz, 25MHz, 77.76MHz,
125MHz and 155.52MHz
• Crystal interface designed for a 27MHz crystal
• Attenuates the phase jitter of the input clock by using a low-cost
fundamental mode crystal
• Customized settings for jitter attenuation and reference tracking
using an external loop filter connection
• FemtoClock NG frequency multiplier provides low jitter, high
frequency output
• Absolute pull range: ±50ppm
• Power supply noise ratio (PSNR): -85dB
• FemtoClock NG VCO frequency: 625MHz
• RMS phase jitter @ 125MHz, using a 27MHz crystal
(12kHz – 20MHz): 0.67ps (typical)
• 3.3V supply voltage
• -40°C to 85°C ambient operating temperature
• Available in lead-free (RoHS 6) package
