Product Description
This is an enhanced high-frequency
3.3V, 125MHz crystal clock oscillator with
superb jitter and low operating current for
Ethernet Passive Optical Network (EPON)
applications.
The output clock signal, generated internally
with a patented oscillator design, is
compatible with LVCMOS logic levels.
Applications
• EPON Optical Network Unit (ONU)
• EPON Optical Line Termination (OLT)
• EPON Gateway
