NB2304AC1DG

Overview

The NB2304AC1DG is a commercial-grade, 3.3 V zero delay clock buffer manufactured by onsemi. It features an integrated PLL that locks to an input clock presented on the REF pin, with feedback driven to the FBK pin from one of the outputs. The device provides four buffered clock outputs organized into two banks (Bank A and Bank B). It guarantees an input-to-output propagation delay of less than 250 ps and an output-to-output skew of less than 200 ps within the same bank. The part operates at frequencies up to 133 MHz and is available in an 8-pin SOIC package.

Feature Summary

• Zero input-output propagation delay adjustable by capacitive load on the FBK input
• Input frequency range of 15 MHz to 133 MHz
• Output-to-output skew less than 200 ps; device-to-device skew less than 500 ps
• Two banks of four outputs with cycle-to-cycle jitter less than 200 ps

Applications

• PC clock distribution
• Workstation clock distribution
• Datacom applications
• Telecom high-performance applications

Procurement Notes

Verify the ordering suffix 'DG' corresponds to the SOIC-8 package with 98 units per rail. Confirm the 'C' designation indicates the commercial temperature range (0°C to 70°C). Ensure the '1' configuration matches the required reference frequency output mode. Check for Pb-Free compliance status as specified in the datasheet.

Selection Notes

Select this component when a zero delay buffer with low skew is required for distributing high-speed clocks. The NB2304AC1DG is suitable for applications needing four outputs derived from a single reference without additional phase shift. Consider the NB2304AC1HDG if higher drive strength and faster rise/fall times are necessary. Verify that the load capacitance requirements (15 pF or 30 pF) align with the target circuit design.

Part Context

The NB2304A series includes variants such as NB2304AI1DG for industrial temperatures and NB2304AC2DG for different frequency configurations (REF, 1/2 X, 2X). The NB2304AC1DG specifically provides reference frequency outputs on both banks. It is part of the NB2304 family designed for versatile clock distribution in performance systems.
