ICS85401AKLFT

Clock Buffers, Drivers Overview

The ICS85401AKLFT is a high-performance 2:1 differential-to-LVDS multiplexer from the HiPerClockS family. It accepts LVPECL, CML, and LVDS inputs on two differential clock pairs and provides one LVDS output pair. The device supports maximum input/output frequencies exceeding 2.5 GHz with a typical propagation delay of 360 ps and part-to-part skew of 100 ps. It operates on a full 3.3V supply (3.135V to 3.465V) within an ambient temperature range of -40°C to 85°C. The component is housed in a compact 3mm x 3mm 16-lead VFQFN package.

Clock Buffers, Drivers Feature Summary

• 2:1 Multiplexing with one LVDS output pair
• Accepts LVPECL, CML, and LVDS differential inputs
• Maximum frequency >2.5 GHz
• Part-to-part skew of 100 ps maximum

Clock Buffers, Drivers Applications

• Space-constrained board designs requiring differential translation
• High-speed clock distribution systems
• Multiplexing differential clock sources for LVDS receivers

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'LF' confirms lead-free (RoHS 6) compliance as specified in the datasheet. Confirm the package type is the 16-lead VFQFN with a 3mm x 3mm body size. Ensure the operating temperature grade matches the -40°C to 85°C specification required for the application environment.

Clock Buffers, Drivers Selection Notes

Select this component when a 2:1 differential-to-LVDS multiplexer is required with a maximum frequency above 2.5 GHz. It is suitable for translating LVPECL, CML, or LVDS signals to LVDS levels without external bias networks for differential inputs. Consider the 100 ps part-to-part skew limit and 460 ps maximum propagation delay for timing-sensitive designs.

Clock Buffers, Drivers Part Context

The ICS85401AKLFT belongs to the HiPerClockS family of high-performance clock solutions originally manufactured by Integrated Device Technology (IDT). IDT was acquired by Renesas Electronics Corporation. The 'AK' designation indicates the specific package and temperature grade, while 'LFT' denotes the lead-free tape and reel packaging configuration.
