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
