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
