NB100EP223FA

Clock Buffers, Drivers Overview

The NB100EP223 is a low skew 1-to-22 differential clock driver designed for high-speed clock distribution. It accepts two differential clock sources (HSTL or LVPECL) via an input multiplexer controlled by an LVTTL CLK_SEL pin. The device provides 22 HSTL-compatible differential outputs, each terminated with 50 Ω to ground. Operating at VCC = 3.0 V to 3.6 V and VCCO = 1.6 V to 2.0 V, it supports frequencies exceeding 500 MHz. Key electrical parameters include a typical propagation delay of 1 ns, within-device skew of 25 ps, and device-to-device skew of 100 ps. The synchronous Output Enable (OE) prevents runt pulses.

Clock Buffers, Drivers Feature Summary

• 1-to-22 differential fanout buffer with HSTL outputs
• Input multiplexer selects between HSTL/LVPECL/HVDS-compatible inputs
• Low skew: 25 ps typical within-device, 100 ps typical device-to-device
• Synchronous Output Enable (OE) eliminates runt clock pulses

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• FPGA and ASIC clocking systems
• Telecommunications infrastructure requiring precise timing alignment

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix to confirm package type and environmental compliance. The 'FA' suffix indicates a standard Lead-Free LQFP-64 package in a tray. The 'G' suffix denotes Pb-Free packaging. Ensure the specific variant matches the required reel or tray quantity specifications provided in the manufacturer's ordering information.

Clock Buffers, Drivers Selection Notes

Select this component when a large number of precisely aligned clock signals are required from a single source. Verify that the system power supplies support VCC between 3.0 V and 3.6 V and VCCO between 1.6 V and 2.0 V. Ensure the input clock signal levels match the selected mode (HSTL or LVPECL) and that the PCB layout accommodates the thermal requirements of the exposed pad LQFP-64 package.

Clock Buffers, Drivers Part Context

This device belongs to the ECLinPS family of high-speed logic components. It is specifically engineered for applications demanding low jitter and minimal skew across multiple output channels. The part integrates both core logic supply and I/O supply domains to optimize performance for HSTL interface standards while maintaining compatibility with legacy PECL signaling through the input multiplexer.

Clock Buffers, Drivers Replacement Considerations

Direct pin-to-pin replacements within the same family may include variants with different output counts or termination schemes. Verify that any substitute maintains the 1-to-22 differential output configuration and compatible voltage levels. Check datasheets for equivalent skew and propagation delay specifications to ensure timing integrity is preserved in the design.
