Product Description
The SDS382 Series is a 2.5V crystal clock oscillator that
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 7x5mm
surface-mount ceramic package.

Applications
The SDS382 Series is an ideal reference clock 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
