ESCRIPTION
The ICS843020-01 is a general purpose, dual out-
put Crystal-to-3.3V Differential LVPECL High Fre-
quency Synthesizer and a member of the
FemtoClocks family of High Performance Clock
Solutions from ICS. The ICS843020-01 is based
on ICS’ 3
rd
generation VCO technology and is capable of sub-
1ps RMS Phase Jitter performance, making it ideal for use in
10 Gigabit Ethernet, 10 Gigabit Fibre Channel, SONET and
Serial ATA applications.
The ICS843020-01 is a highly flexible programmable synthe-
sizer capable of generating output frequencies over a range of
70MHz to 680MHz. The output frequency can be programmed
in small step sizes as low as 250
k
Hz when using a 16MHz
crystal,
÷
8 input divider, and output divider =
÷
8.
