ICS858018AK

Clock Buffers, Drivers Overview

The ICS858018AK is a high-performance 2:1 differential-to-LVPECL multiplexer from the HiPerClockS family. It features two differential input pairs (IN0/nIN0 and IN1/nIN1) with internal 50Ω termination resistors, selectable via VT0/VT1 pins to support LVDS, LVPECL, CML, and SSTL signal levels. The device provides one differential LVPECL output pair (Q/nQ). It operates on a single supply voltage of 2.375V to 3.63V or dual supplies for ECL compatibility. The maximum output frequency is 2GHz, with a typical propagation delay of 350ps and part-to-part skew of 250ps. It is housed in a compact 16-lead VFQFN package measuring 3mm x 3mm.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix when sourcing components. The 'LF' suffix indicates a lead-free configuration that is RoHS compliant. Standard versions without the 'LF' suffix are also available. Confirm whether tube or tape-and-reel packaging is required for the specific order quantity.

Clock Buffers, Drivers Selection Notes

Select this component when a 2:1 differential multiplexer with built-in termination is needed. Ensure the input signal type matches the supported levels (LVDS, LVPECL, CML, SSTL). Verify that the operating voltage range (2.375V to 3.63V) aligns with the system power supply. Consider the 3mm x 3mm package size for space-limited applications.

Clock Buffers, Drivers Part Context

The ICS858018 belongs to the HiPerClockS family of high-performance clock solutions originally developed by IDT, which was later acquired by Renesas Electronics Corporation. This family focuses on low-skew, high-frequency clock management devices for demanding digital applications.

Clock Buffers, Drivers Replacement Considerations

The datasheet notes pin compatibility with the SY58011U. Verify functional equivalence and electrical specifications before substituting.
