Clock Generators & Support Products

NB2309AI1DTR2G Description

The NB2309AI1DTR2G from onsemi is a high-performance Zero Delay Buffer (ZDB) designed for precise clock distribution in demanding electronic systems. This 1:9 ratio clock buffer operates within a 3V to 3.6V supply range, supporting frequencies up to 133.33MHz. Housed in a compact 16-pin TSSOP package and delivered in Tape & Reel (TR), it is optimized for surface-mount applications. Although marked as Obsolete, it remains a reliable choice for legacy designs requiring low-jitter clock synchronization. The device features an integrated PLL with bypass capability, ensuring minimal phase error and high signal integrity.

NB2309AI1DTR2G Features

• Zero Delay Buffer: Eliminates clock skew between input and output signals, critical for synchronous systems.
• 1:9 Clock Distribution: Drives up to nine outputs from a single input, reducing component count.
• Wide Voltage Range: Operates at 3V–3.6V, compatible with common logic levels.
• PLL with Bypass: Allows flexible clock management, enabling either PLL-synchronized or direct buffering.
• Low-Jitter Performance: Ideal for applications requiring precise timing, such as networking and telecom.
• RoHS3 Compliant & REACH Unaffected: Meets environmental regulations for hazardous substances.
• Surface-Mount Design: 16-TSSOP package ensures space-efficient PCB integration.

NB2309AI1DTR2G Applications

• Telecommunications Equipment: Ensures synchronized clocking in routers, switches, and base stations.
• Data Storage Systems: Maintains timing accuracy in RAID controllers and SSDs.
• Industrial Automation: Provides stable clock signals for PLCs and motion controllers.
• Legacy Embedded Systems: Suitable for upgrades or repairs of older designs requiring zero-delay buffering.
• Test & Measurement Instruments: Delivers low-jitter clocks for oscilloscopes and signal analyzers.

Conclusion of NB2309AI1DTR2G

The NB2309AI1DTR2G is a robust Zero Delay Buffer offering high-frequency stability, low skew, and flexible PLL operation. While obsolete, its 1:9 clock distribution and 3.3V compatibility make it a viable solution for legacy and specialized applications. Engineers in telecom, data storage, and industrial systems can leverage its precision timing capabilities to enhance system reliability. For new designs, verify alternative models, but for existing implementations, this IC remains a dependable choice.
