NB2305AI1DTG

Overview

The NB2305AI1DTG is a zero-delay buffer integrated circuit manufactured by onsemi, belonging to the NB2305A series. It functions as a phase-locked loop (PLL) clock driver with one input and five outputs. The device operates within a supply voltage range of 3.0 V to 3.6 V, typically at 3.3 V, and supports output frequencies from 15 MHz to 133 MHz. Designed for CMOS inputs and outputs, it ensures minimal clock skew in high-speed digital systems. The component is housed in an 8-TSSOP package with a width of 4.40 mm and is rated for operation between -40°C and +85°C.

Feature Summary

• Zero-delay PLL architecture providing low-skew clock distribution
• Five CMOS outputs driven by a single CMOS input
• Operational frequency range up to 133 MHz
• Single-supply operation at 3.3 V (3.0 V to 3.6 V)

Applications

• High-speed data acquisition systems requiring precise clock synchronization
• Telecommunications equipment utilizing serial-to-parallel conversion
• Digital signal processing circuits needing low-jitter clock buffers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official material declarations. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) prior to procurement, as availability may be restricted.

Selection Notes

Select this model when a five-output zero-delay buffer is required for 3.3 V logic families. Ensure the application frequency does not exceed 133 MHz. Verify that the 8-TSSOP package dimensions fit the PCB layout constraints. Consider alternative pin counts if more than five outputs are needed.

Part Context

This part belongs to the NB2305A family of 3.3 V zero-delay clock buffers. It shares functional similarities with other members like the NB2304A (four outputs) and NB2308A (eight outputs). The 'DTG' suffix indicates the specific TSSOP-8 packaging and lead-free manufacturing process compliant with environmental standards.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-manufacturer equivalents such as Microchip PL123 series only after verifying electrical parameter compatibility.
