Product Features
Recommended Land Pattern:
• Very low phase jitter - 0.5ps RMS
• Thicker crystal for improved reliability
• Low output current - 20mA max.
• Industrial Temperature Range
• Pb-free & RoHS compliant
Product Description
This is an enhanced high-frequency 3.3V,
156.25MHz crystal clock oscillator with
superb jitter and low operating current for
10 Gigabit Ethernet applications. The output
clock signal, generated internally with a
patented oscillator design, is compatible
with LVCMOS logic levels.
