Product Description
The FD Series could working with 1.8~3.3V
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 LVCMOS/LVTTL
logic levels. The device, available on tape and
reel, is contained in a 5.0x3.2mm surface-
mount ceramic package.
The FD Series is an ideal reference clock for
compact, high-density applications requiring
low jitter or tight stability, including:
Product Features
Less than 1.5ps RMS jitter with fundamental or
overtone design
1.8~3.3V CMOS compatible logic levels
Pin-compatible with standard 5.0x3.2mm
packages
Designed for standard reflow and washing
techniques
Low power standby mode
Available on tape & reel; 1000pcs/reel
Pb-free and RoHS/Green compliant
Ethernet
Fiber Channel
Serial Attached SCSI (SAS)
Server & Storage platforms
SONET/SDH line cards
T1/E1, T3/E3 line cards

External high-frequency power
decoupling is recommended. (See test
circuit for minimum recommendation). To
ensure optimal performance, do not
route traces beneath the package.

Electrical Performance
Notes:
1. As specified. Stability includes all combinations of operating temperature, load changes, rated input (supply) voltage changes, initial calibration
tolerance (25°C), aging (1 year at 25°C average effective ambient temperature), shock and vibration.
