2309NZ-1HPGGI

Overview

The Renesas 2309NZ-1HPGGI is a low phase noise, high-speed PLL-based zero delay buffer operating at 3.3V. It features a 1:9 input-to-output ratio, distributing one clock signal to nine LVTTL outputs with frequencies up to 133.33 MHz. The device utilizes an on-chip PLL for zero input-output delay and provides output skew of less than 250 ps. Packaged in a 16-pin TSSOP (0.65 mm pitch), it supports an industrial temperature range of -40°C to 85°C and includes tri-state capabilities for board-level testing.

Feature Summary

• Zero delay buffer architecture using proprietary low jitter PLL techniques
• Nine low skew (<250 ps) LVTTL outputs with 12 mA drive capability
• Operating frequency range from 10 MHz to 133.33 MHz
• Industrial temperature rating (-40°C to 85°C) and 3.3V supply voltage

Applications

• High-speed clock distribution networks
• System-on-chip (SoC) clock generation
• Data communication equipment timing
• Network infrastructure synchronization

Procurement Notes

Verify the specific suffix 'I' against official Renesas documentation to confirm if it denotes a specific tape-and-reel packaging variant or environmental compliance level distinct from the standard tube packaging. Confirm assembly location and moisture sensitivity level (MSL 1) requirements for surface mount processes.

Selection Notes

Select this component when a single reference clock must be distributed to multiple synchronous loads with minimal skew. Ensure the system requires LVTTL output levels and operates within the 3.3V domain. The -1H variant indicates high drive strength; verify if standard drive versions are sufficient for lower load capacitance applications to optimize power consumption.

Part Context

This part belongs to the IDT 2309N family of zero delay buffers, now manufactured by Renesas Electronics following its acquisition of Integrated Device Technology (IDT). The 2309 series is designed for high-performance clock distribution, replacing older discrete buffering solutions with integrated PLL functionality to reduce jitter and board space.

Replacement Considerations

Direct pin-compatible alternatives include the 2309NZ-1HPGG (commercial temperature range) and 2309A-1 variants. Verify that replacement parts maintain the same 1:9 fan-out ratio and LVTTL output compatibility.
