2308-1HDCG

Overview

The Renesas Electronics Corporation 2308-1HDCG is a high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution applications. It operates within a frequency range of 10 MHz to 133 MHz and accepts a single LVCMOS input, distributing the signal to eight outputs organized into two banks of four. The device features an external feedback pin to synchronize outputs with the input clock, achieving output skew of less than 200 ps and cycle-to-cycle jitter under 200 ps. It functions at a supply voltage of 3.3 V (3 V to 3.6 V) and is housed in a 16-pin SOIC package.

Feature Summary

• Zero-delay PLL architecture aligns output phase with the incoming clock input
• Distributes one input to two independent banks of four outputs each
• External feedback pin allows user control over delay between input and outputs
• Supports separate output enable controls for each output bank

Applications

• High-speed clock distribution systems
• Clock multiplication and prescaling circuits
• System testing modes requiring direct input drive

Part Context

The 2308-1HDCG belongs to the IDT 2308 family of zero-delay buffers. This specific suffix indicates a 1x multiplication ratio configuration packaged in a 16-pin SOIC format. The component is part of Renesas' portfolio for managing clock signals in digital logic environments where precise timing alignment is critical.

Replacement Considerations

Public documentation lists the Texas Instruments CDCVF25081PW and CDCVF25081PWR as upgrade alternatives for related discontinued models in this series.
