NB100LVEP224FARG

Clock Buffers, Drivers Overview

The NB100LVEP224 is a low skew 1-to-24 differential clock driver designed for high-performance clock distribution in 2.5V and 3.3V systems. It accepts two differential ECL/PECL clock sources via an input multiplexer selected by the CLK_SEL pin. The device features synchronous Output Enable (OE) to prevent runt pulses. Key electrical parameters include a maximum operating frequency exceeding 1 GHz, typical propagation delay of 650 ps, and typical output-to-output skew of 20 ps. It operates in LVPECL mode with VCC ranging from 2.375 V to 3.8 V (VEE = 0 V) or NECL mode with VEE from -2.375 V to -3.8 V (VCC = 0 V).

Clock Buffers, Drivers Feature Summary

• 1:24 Differential Clock Driver with Input Multiplexer
• Low Skew: 20 ps Typical Output-to-Output, 75 ps Typical Device-to-Device
• Synchronous Output Enable (OE) Prevents Runt Pulses
• LVDS-Compatible CLOCK Inputs with Internal Pulldown Resistors

Clock Buffers, Drivers Applications

• High-speed clock distribution networks requiring large fan-out
• Systems demanding precisely aligned low skew signals
• 2.5V and 3.3V LVPECL/NECL logic environments

Clock Buffers, Drivers Procurement Notes

Verify package suffixes against ordering information. The FA suffix denotes a thermally enhanced 64-lead LQFP tray package. The FARG suffix typically indicates a tape and reel variant; confirm specific reel quantities (e.g., 1500 units for FAR2) and moisture sensitivity level (Level 3) requirements during procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a single source must drive up to 24 differential outputs with minimal skew. Ensure the PCB design accommodates the thermally enhanced LQFP-64 package, specifically utilizing the exposed pad connected to VEE for heat dissipation. Verify that input clocks meet the LVDS-compatible common mode range if using LVDS sources.

Clock Buffers, Drivers Part Context

This part belongs to the NB100LVEP family of ECL/PECL clock drivers. It provides higher fan-out capabilities compared to lower-channel variants like the NB100LVEP210 (1:5) or NB100LVEP222 (2:1:15), making it suitable for complex synchronization architectures requiring extensive signal branching.
