Features

? Fourth Generation FemtoClock? NG technology

? Two LVPECL output pairs

? Each output supports independent frequency selection at

19.44MHz, 77.76MHz, 155.52MHz and 622.08MHz

? Two differential inputs support the following input types: LVPECL,

LVDS, LVHSTL, HCSL

? Accepts input frequencies from 8kHz to 156.25MHz including

8kHz,19.44MHz, 25MHz, 62.5MHz, 77.76MHz, 125MHz,

155.52MHz and 156.25MHz

? Crystal interface designed for a 27MHz, 10pF parallel resonant

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 rejection (PSNR): -95dB (typical)

? FemtoClock NG VCXO frequency: 2488.32MHz

? RMS phase jitter @ 155.52MHz, using a 27MHz crystal

(12kHz – 20MHz): 0.674ps (typical)

? 3.3V supply voltage

? 0°C to 70°C ambient operating temperature

? Available in lead-free (RoHS 6) package
