ICS853014BGLF

Clock Buffers, Drivers Overview

The ICS853014BGLF is a low skew, high performance 1-to-5 differential-to-LVPECL/ECL fanout buffer from the HiPerClockS family. It features five differential LVPECL/ECL outputs and two selectable differential clock inputs (PCLKx/nPCLKx) that accept LVPECL, LVDS, CML, or SSTL levels. The device operates with a maximum output frequency exceeding 2 GHz. In LVPECL mode, the supply voltage range is VCC = 2.375V to 3.8V with VEE at 0V. In ECL mode, VCC is 0V and VEE ranges from -3.8V to -2.375V. It supports an ambient operating temperature of -40°C to 85°C.

Clock Buffers, Drivers Feature Summary

• Five differential LVPECL/ECL outputs
• Two selectable differential clock inputs accepting LVPECL, LVDS, CML, SSTL
• Maximum output frequency > 2 GHz
• Output skew: 13 ps typical; Part-to-part skew: 60 ps typical

Clock Buffers, Drivers Applications

• Clock distribution systems requiring well-defined performance and repeatability
• High-speed digital interfaces utilizing LVPECL or ECL signaling
• Differential clock buffering for multi-load applications

Clock Buffers, Drivers Procurement Notes

Verify the RoHS 6 lead-free status indicated by the LF suffix against current environmental compliance requirements. Confirm the package type is the 20-lead TSSOP (6.5mm x 4.4mm). Ensure the ordering suffix matches the required shipping packaging, such as tube or tape & reel, as specified in the manufacturer's ordering information table.

Clock Buffers, Drivers Selection Notes

Select this component when a 1-to-5 fanout ratio with sub-nanosecond propagation delay is required. Verify input signal compatibility with LVPECL, LVDS, CML, or SSTL standards. Ensure the system power supply aligns with either the 2.5V/3.3V LVPECL mode or the negative voltage ECL mode specifications. Check thermal constraints, as total power dissipation can reach approximately 477.7mW with all outputs loaded.

Clock Buffers, Drivers Part Context

The ICS853014BGLF belongs to the HiPerClockS family of high-performance clock solutions originally developed by IDT. It serves as a low-skew buffer designed to distribute differential clock signals to multiple destinations. The device is pin-compatible with MC100LVEP14 and SY100EP14U, facilitating potential direct replacements in existing designs utilizing those specific legacy components.

Clock Buffers, Drivers Replacement Considerations

The datasheet explicitly states pin compatibility with MC100LVEP14 and SY100EP14U. These part numbers may serve as functional substitutes if electrical parameters meet design requirements.
