3.3V PECL Low Jitter 155.52MHz GPON XO

SNGPON155

Application Specific Crystal Oscillator 7.0 x 5.0mm

Product Features

• Very low phase jitter - 0.5ps RMS

• Thicker crystal for improved reliability

• Pb-free & RoHS compliant

• Industrial temperature range

Product Description

The SN series 3.3V, 155.52MHz crystal

clock oscillator achieves superb jitter for

GPON applications. The output clock

signal, generated internally with a patented

oscillator design, is compatible with LVPECL

logic levels. The device, available on tape

and reel, is contained in a 7.0 x 5.0mm

surface-mount ceramic package.

Applications

• GPON Optical Network Unit (ONU)

• GPON Optical Line Termination (OLT)

• GPON Gateway

*Extended high frequency power decoupling is recommended (see test circuit for minimum

recommendation). To ensure optimal performance, do not route RF traces beneath the

package.
