Product Description
The LD series 2.5V, 155.52MHz crystal clock
oscillator achieves superb jitter for GPON
applications. The output clock signal,
generated internally with a custom oscillator
design, is compatible with LVDS logic levels.
The device, available on tape and reel, is
contained in a 5.0 x 3.2mm 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.
