ICS853011CGLF

Clock Buffers, Drivers Overview

The ICS853011CGLF is a low skew, high performance 1-to-2 differential-to-2.5V/3.3V LVPECL/ECL fanout buffer from the HiPerClockS family. It operates on either a 2.5V or 3.3V power supply with VCC ranging from 2.375V to 3.8V (VEE = 0V) for LVPECL mode, or VEE ranging from -3.8V to -2.375V (VCC = 0V) for ECL mode. The device features one differential PCLK/nPCLK input pair accepting LVPECL, LVDS, CML, and SSTL levels, and two differential outputs. It supports output frequencies exceeding 2.5GHz, with a maximum propagation delay of 330ps, output skew of 15ps, and part-to-part skew of 150ps. Additive phase jitter is typically 0.16ps RMS.

Clock Buffers, Drivers Feature Summary

• Two differential 2.5V or 3.3V LVPECL/ECL outputs
• One differential PCLK, nPCLK input pair accepting LVPECL, LVDS, CML, SSTL
• Output frequency >2.5GHz with additive phase jitter of 0.16ps (typical)
• Output skew: 15ps (maximum); Part-to-part skew: 150ps (maximum)

Clock Buffers, Drivers Applications

• Clock distribution in high-performance computing systems
• Telecommunications equipment requiring precise timing
• Data acquisition systems demanding low skew clock signals

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'LF' confirms lead-free and RoHS compliance as specified in the datasheet's ordering information table. Ensure the package type matches the required 8-lead TSSOP form factor. Confirm the ambient operating temperature range meets system requirements of -40°C to +85°C. Cross-reference the manufacturer designation, noting the product originates from IDT which is now part of Renesas Electronics.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential clock source needs to drive two separate LVPECL or ECL loads with minimal skew. It is suitable for applications requiring translation of various differential input standards (LVDS, CML, SSTL) to LVPECL/ECL outputs. Consider the thermal resistance (θJA) of 101.7°C/W for the TSSOP package when calculating junction temperature under worst-case power dissipation conditions at 3.8V supply.

Clock Buffers, Drivers Part Context

The ICS853011CGLF belongs to the HiPerClockS family of high-performance clock solutions originally developed by Integrated Device Technology (IDT). The 'G' suffix denotes the 8-lead TSSOP package, while 'LF' indicates a lead-free configuration compliant with RoHS standards. This specific part number represents the tube packaging variant of the lead-free TSSOP version.

Clock Buffers, Drivers Replacement Considerations

The datasheet explicitly states the device is pin compatible with MC100LVEP11 and SY100EP11U. These parts can be considered direct replacements if electrical characteristics such as skew and jitter meet the specific application requirements.
