ICS843020-01
FEMTOCLOCKS 680MHZ, CRYSTAL-TO-
3.3V DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS843020-01 is a general purpose, dual output
Crystal-to-3.3V Differential LVPECL High Frequency
Synthesizer. The ICS843020-01 is based on I
DT’s 3rd
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
synthesizer 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 250kHz when
using a 16MHzcrystal,
÷8 input divider, and output divider =
÷8.
