Product Description
The FD Series 2.5V 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 LVCMOS/LVTTL logic levels. The device,
available on tape and reel, is contained in a
5.0 x 3.2mm surface-mount ceramic package.
Applications
The FD Series is ideal for compact, high-
density applications requiring low jitter or tight
stability, including:
Ethernet•
EPON•
Fibre Channel•
Serial Attached SCSI (SAS)•
Server & Storage platforms•
SONET/SDH linecards•
T1/E1, T3/E3 linecards•
DSLAM•
802.11a/b/g WiFi•
