2309-1DCG

Overview

The Renesas Electronics 2309-1DCG is a zero-delay buffer IC designed for low phase noise and high-speed clock distribution. It utilizes a proprietary Phase Locked Loop (PLL) technique to provide nine low-skew outputs at frequencies up to 133 MHz with a 3.3 V supply. The device operates within a voltage range of 3 V to 3.6 V and features an input propagation delay of 0 ps maximum. Packaged in a 16-SOIC format, it supports LVTTL inputs and outputs, ensuring precise timing alignment for digital systems.

Feature Summary

• Zero-delay PLL architecture ensures output signals are aligned with the input reference without added latency.
• Provides nine LVCMOS/LVTTL outputs capable of operating at frequencies up to 133 MHz.
• Operates on a single 3.3 V power supply with a specified range of 3 V to 3.6 V.
• Available in a 16-pin SOIC surface-mount package suitable for automated assembly.

Applications

• Clock distribution networks requiring low skew and zero delay.
• High-speed digital systems utilizing LVCMOS or LVTTL logic families.
• FPGA and ASIC clock buffering applications demanding precise timing alignment.

Part Context

The 2309-1DCG belongs to the IDT 2309 family of zero-delay buffers. This series is characterized by its ability to generate multiple low-skew outputs from a single input using an on-chip PLL. The '1' designation typically indicates the base part version, while the suffix specifies the package type and temperature range. This component serves as a critical interface for synchronizing clocks across complex digital circuits.

Replacement Considerations

The IDT2309-1HDCG is a documented alternate part number for this component. Designers should verify that the specific package variant matches the PCB footprint requirements before substitution.
