NB2305AI1HDTR2G

Overview

The NB2305AI1HDTR2G is a zero-delay buffer integrated circuit manufactured by onsemi, belonging to the NB2305A series. It functions as a phase-locked loop (PLL) clock buffer with one input and five outputs. The device operates within a supply voltage range of 3 V to 3.6 V, typically at 3.3 V, and supports output frequencies from 15 MHz to 133 MHz. It utilizes silicon technology and is housed in an 8-TSSOP package with a width of 4.40 mm. The component is rated for operation between -40°C and +85°C and features CMOS input and output logic levels without differential signaling capabilities.

Feature Summary

• Zero-delay PLL architecture providing five buffered clock outputs from a single input
• Operational frequency range spanning 15 MHz to 133 MHz
• Supply voltage compatibility from 3 V to 3.6 V
• Surface-mount packaging in an 8-TSSOP case outline

Applications

• Clock distribution in high-speed digital systems
• Buffering reference clocks for data converters or processors
• Timing synchronization in communication equipment

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking distributor stock levels, as new production has ceased. Buyers must confirm end-of-life status and potential obsolescence notices before procurement planning. Alternative sourcing may involve surplus markets or qualified replacement components.

Selection Notes

Select this part when a single-ended 1:5 clock fan-out with minimal skew is required for 3.3 V logic systems. Ensure the design accommodates the 133 MHz maximum frequency limit. Verify that the TSSOP-8 footprint matches the PCB layout constraints. Consider the obsolete status when designing for long-term production runs.

Part Context

The NB2305AI1HDTR2G is a tape-and-reel variant of the NB2305A family. It shares functional specifications with other packages like the SOIC-8 versions but differs in physical form factor and shipping container. The 'H' denotes the SOIC/TSSOP style, while 'DTR2G' indicates the specific reel packaging and RoHS compliance attributes defined by onsemi.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-compatible replacements should be verified against current manufacturer catalogs or cross-reference databases.
