2309-1DCG8

Overview

The Renesas Electronics 2309-1DCG8 is a zero-delay clock buffer IC designed for high-speed clock distribution. It accepts one reference input and drives nine outputs, operating at frequencies up to 133 MHz with a 3V to 3.6V supply voltage. The device utilizes an on-chip PLL to align output phase with the input reference, achieving low skew characteristics. It is housed in a 16-pin SOIC package (0.154 inch width) and supports LVTTL input/output logic levels. The component operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Zero-delay buffer architecture using internal PLL feedback from CLKOUT pad
• 1:9 fan-out ratio distributing one input to nine outputs
• Maximum operating frequency of 133 MHz
• Low skew performance with propagation delay specifications

Applications

• High-speed clock distribution networks
• System synchronization in digital circuits
• Clock buffering for memory interfaces

Part Context

This component belongs to the 2309 series of zero-delay buffers. It is functionally related to variants such as the 2309-1HDCG, which offers higher drive strength, and the 2309NZ-1HDCG8, which shares similar packaging but may differ in specific electrical characteristics or revision status. The '8' suffix typically denotes tape-and-reel packaging.
