LD Series Crystal Clock Oscillator (XO)
5.0 x 3.2mm
LD
Product Features
• 38.88 to 162 MHz Frequency Range
• <1 ps RMS jitter with non-PLL design
•Designed for standard reflow & washing
techniques
•IBIS models available
• Pb-free & RoHS/Green compliant
Product Description
The LD Series 3.3V crystal clock oscillator
achieves superb jitter and stability over a broad
range of operating conditions and frequencies.
The output clock signal, generated internally
with a non-PLL 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
The LD Series is ideal for high-speed
applications requiring low jitter, including:
• 1/10 Gigabit Ethernet
• 2/4/10G FibreChannel
•Serial Attached SCSI (SAS)
•Server & Storage platforms
• SONET/SDH linecards
•Passive Optical Network (PON) devices
• HD Video Systems
