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.
