NB2308AI1HDTR2G

Overview

The NB2308AI1HDTR2G is a 3.3 V zero delay clock buffer from onsemi, designed for high-speed clock distribution. It features an internal PLL that locks to a reference clock input and provides eight low-skew outputs organized into two banks of four. The device supports an input frequency range of 15 MHz to 133 MHz with a maximum operating frequency of 133.3 MHz. It operates within a supply voltage range of 3.0 V to 3.6 V and is rated for industrial temperatures between -40°C and +85°C. Packaged in a 16-pin TSSOP (DT suffix) in tape and reel format, it utilizes advanced CMOS technology.

Feature Summary

• Zero input-to-output propagation delay adjustable via capacitive load on the feedback pin
• Input-to-output propagation delay guaranteed less than 250 ps
• Output-to-output skew less than 200 ps; device-to-device skew less than 700 ps
• Cycle-to-cycle jitter less than 200 ps at 66.67 MHz

Applications

• High-speed clock distribution systems
• Multi-device synchronization requiring low skew
• Industrial temperature environment clock buffering

Procurement Notes

Verify the package type matches the required footprint, as this part number specifies the TSSOP-16 variant. Confirm the 'I' suffix indicates the industrial temperature grade (-40°C to +85°C). Ensure the 'R2' suffix corresponds to the tape and reel shipping configuration. Check current availability status as manufacturing schedules may change.

Selection Notes

Select this component when a 1:8 fanout with zero delay characteristics is required. The 'H' designation indicates a high-drive version with faster rise and fall times compared to standard variants. Ensure the application load capacitance aligns with the specified limits (15 pF for frequencies above 100 MHz) to maintain timing specifications.

Part Context

This part belongs to the NB2308A family of zero delay buffers. The specific suffixes define its attributes: 'I' for industrial temperature range, 'H' for high-drive outputs, 'D' for TSSOP-16 package, and 'R2' for tape and reel packaging. It is functionally distinct from the SOIC-16 version (suffix 'D' without 'T') and commercial grade versions (suffix 'C').
