2309NZ-1HPGG

Overview

The Renesas Electronics Corporation 2309NZ-1HPGG is a clock fan-out buffer IC designed for high-speed signal distribution. It accepts one LVTTL input and provides nine LVTTL outputs with a maximum operating frequency of 133.33 MHz. The device operates on a single supply voltage ranging from 3V to 3.6V. It is housed in a 16-TSSOP package with a width of 4.40mm. This component functions as a zero-delay buffer, aligning the phase between the incoming clock and output clocks to minimize jitter and skew in digital systems.

Feature Summary

• 1:9 Fan-Out Ratio: Distributes a single clock input to nine independent outputs.
• High Frequency Operation: Supports clock frequencies up to 133.33 MHz.
• LVTTL Interface: Compatible with Low Voltage Transistor-Transistor Logic standards for both input and output signals.
• Compact Packaging: Utilizes a 16-TSSOP surface-mount package (0.173"/4.40mm width) for space-efficient board designs.

Applications

• Clock distribution networks in high-speed digital circuits.
• Buffering reference clocks for multiple synchronous components.
• System timing architectures requiring low-skew signal propagation.

Procurement Notes

Verify the specific suffix 'I' if industrial temperature range (-40°C to 85°C) is required, as the standard 'G' variant typically specifies a commercial range (0°C to 70°C). Confirm RoHS compliance status and moisture sensitivity level (MSL 1) during storage planning. Ensure the 16-TSSOP footprint matches the PCB layout specifications before procurement.

Selection Notes

Select this component when a single clock source must drive nine loads with minimal phase deviation. Ensure the system logic levels match LVTTL requirements. For applications requiring extended temperature ranges beyond commercial limits, verify the availability of the industrial grade variant. Consider the 133.33 MHz limit when designing for higher frequency requirements.

Part Context

This part belongs to the 2309N series of clock buffers manufactured by Renesas Electronics. The 'Z' suffix often denotes specific packaging or testing configurations within the distributor catalog, while '1H' indicates a high-drive version compared to base models. The 'PGG' suffix identifies the specific TSSOP package type and lead finish.

Replacement Considerations

Direct replacements include other 1:9 LVTTL fan-out buffers from the same family, such as the 2309NZ-1HDCG8, which offers the same electrical characteristics but in a 16-SOIC package. Verify pin compatibility and thermal performance when substituting packages.
