NOTE: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the
device. These ratings are stress specifications only. Functional operation of product at these conditions or any
conditions beyond those listed in the DC Characteristics or AC Characteristics is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.

The ICS843020-01 is a general purpose, dual output Crystal-to-3.3V Differential LVPECL High Frequency Synthesizer and a member of the FemtoClocks™ family of High Performance Clock Solutions from ICS. The ICS843020-01 is based on ICS' 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 16MHz crystal, ÷8 input divider, and output divider = ÷8.
