NB2308AC5HDTG

Overview

The NB2308AC5HDTG is a commercial-grade, 3.3 V zero delay clock buffer manufactured by onsemi in a 16-pin TSSOP package. It features an integrated PLL that locks to a reference clock input and distributes the signal across eight outputs organized into two banks of four. The device supports multiple frequency configurations, including reference, 2X, and 4X multiplication, determined by the feedback path connection. Key electrical specifications include an input frequency range of 15 MHz to 133 MHz, output-to-output skew less than 200 ps, and cycle-to-cycle jitter under 200 ps.

Feature Summary

• Zero delay buffer with adjustable input-to-output propagation delay via capacitive load on the FBK pin
• Multiple configuration options (x1, x2, x3, x4, x5H) for reference or multiplied clock distribution
• Two three-stateable output banks controlled by S1 and S2 select inputs
• Low-skew performance with output-to-output skew < 200 ps and device-to-device skew < 700 ps

Applications

• High-speed clock distribution in computing systems
• Multi-device synchronization requiring low skew
• Clock generation for digital logic circuits

Procurement Notes

Verify the ordering suffix 'DTG' corresponds to the TSSOP-16 package and Pb-Free status as defined in the manufacturer's ordering information table. Confirm the 'C5H' designation matches the specific high-drive REF/2 configuration required for the application circuit design.

Selection Notes

Select this component when a 3.3 V supply and TSSOP-16 footprint are required. Ensure the application utilizes the C5H configuration, which provides reference clocks on both banks. Verify that the load capacitance requirements align with the 15 pF limit for frequencies up to 133 MHz to maintain specified timing parameters.

Part Context

This part belongs to the NB2308A family of zero delay buffers. The 'C' indicates a commercial temperature range (0°C to 70°C), while 'I' variants support industrial temperatures (-40°C to 85°C). The 'H' suffix denotes a high-drive version with faster rise and fall times compared to standard drive versions.

Replacement Considerations

NB2308AI5HDTG serves as the industrial temperature variant of this component. Other family members like NB2308AC1HDTG or NB2308AC2HDTG offer different frequency multiplication configurations but share the same package and voltage specifications.
