The FN Series is a 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 CMOS/TTL
logic levels. The device, available on tape and reel,
is contained in a 5x7mm surface-mount ceramic
package.

Applications
The FN Series is an ideal reference clock for
applications requiring low jitter or tight stability,
including:
• Ethernet
• FibreChannel
• Serial Attached SCSI (SAS)
• Server & Storage platforms
• SONET/SDH linecards
• T1/E1, T3/E3 linecards
• DSLAM
• 802.11a/b/g WiFi
Note: After July 1, 2007, a Saronix - eCera part number following the
above format will be assigned upon confirmation of exact customer
requirements.
