NB100EP223FAR2

Clock Buffers, Drivers Overview

The NB100EP223FAR2 is a low skew 1-to-22 differential clock driver manufactured by onsemi. It accepts two differential clock sources (HSTL, LVPECL, or LVDS) via an input multiplexer selected by the LVTTL-compatible CLK_SEL pin. The device provides 22 HSTL-compatible differential outputs with synchronous Output Enable (OE). Operating at VCC = 3.0 V to 3.6 V and VCCO = 1.6 V to 2.0 V, it supports maximum 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. It is housed in a thermally enhanced 64-lead LQFP package.

Clock Buffers, Drivers Feature Summary

• 1-to-22 Differential Clock Driver with Input Multiplexer
• Low Skew: 25 ps Typical Within-Device, 100 ps Typical Device-to-Device
• HSTL Compatible Outputs Driving 50 Ohms to Ground
• Synchronous Output Enable (OE) Prevents Runt Pulses
• LVDS-Compatible CLOCK Inputs

Clock Buffers, Drivers Applications

• High-speed clock distribution systems requiring large fan-out
• Low voltage applications needing precisely aligned low skew signals
• Systems interfacing between LVDS, PECL, and HSTL domains

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'R2' corresponds to the tape and reel packaging configuration containing 1500 units per reel as specified in the manufacturer's ordering information. Confirm that the specific revision level matches the design requirements, noting that product specifications may be subject to change without notice.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source must be distributed to 22 destinations with minimal skew. Ensure the system design accommodates the dual power supply requirement (VCC for core logic and VCCO for HSTL outputs). Verify that the PCB layout supports the recommended thermal land pattern and via array to manage heat dissipation effectively given the high-speed bipolar integrated circuit nature of the device.

Clock Buffers, Drivers Part Context

This part belongs to the NB100EP series of ECLinPS family devices, designed for high-performance clock distribution. The 'FA' suffix indicates the 64-lead LQFP package type, while 'R2' denotes the tape and reel shipping format. It serves as a bridge between various differential signaling standards, facilitating complex system architectures that require precise timing alignment across multiple components.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, ensure compatibility with the 64-lead LQFP footprint, similar skew characteristics, and matching voltage levels for both core and I/O supplies.
