Overview
The ICS858012AKLF is a low skew, 1-to-2 differential-to-LVPECL fanout buffer from the HiPerClockS family. It accepts differential inputs such as LVDS, LVPECL, LVHSTL, SSTL, and HCSL via internally terminated IN/nIN pins. The device provides two differential LVPECL outputs with a typical output frequency of 2GHz and output skew under 15ps. Operating voltage ranges from 2.375V to 3.63V for VCC with VEE at 0V. It features a propagation delay of 350ps and operates within an ambient temperature range of -40°C to +85°C in a 16-pin VFQFN package.

Procurement Notes
Verify the 'FL' suffix indicates lead-free compliance and RoHS 6 status. Confirm the 'K' suffix corresponds to the 16-lead VFQFN package. Ensure the component meets the specified -40°C to +85°C operating temperature range for the target application environment.
Selection Notes
Select this component when interfacing various differential clock sources like LVDS or HCSL to LVPECL loads requiring low skew. Ensure the design supports the 2.375V to 3.63V VCC supply range. Verify that the 16-pin VFQFN package dimensions fit the space-constrained layout requirements.
Part Context
The ICS858012 belongs to the HiPerClockS family of high-performance clock solutions. It is pin-compatible with the SY58012U. The device is designed for demanding high-speed applications where minimal signal distortion and precise timing are critical.
Replacement Considerations
The datasheet notes pin compatibility with the SY58012U. Verify functional equivalence before substitution.
FAQ
What differential input levels does the ICS858012 support?
The IN/nIN pair can accept LVPECL, LVDS, LVHSTL, SSTL, and HCSL differential input levels.
How should unused LVPECL outputs be handled?
Unused LVPECL outputs can be left floating, but it is recommended that no trace be attached to them.
What is the maximum recommended junction temperature?
The maximum recommended junction temperature for HiPerClockS devices is 125°C.
