2308-2HDCG

Overview

The Renesas Electronics Corporation 2308-2HDCG is a 3.3V Zero Delay Clock Multiplier designed for high-speed clock distribution and multiplication applications. It operates within a frequency range of 10 MHz to 133 MHz, utilizing a Phase-Lock Loop (PLL) to align the phase between the incoming clock and output clocks. The device features eight LVCMOS outputs organized into two banks of four, with separate enable controls for each bank. Key electrical parameters include an 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 and is housed in a 16-pin SOIC package.

Feature Summary

• Zero delay operation synchronizes outputs directly to the input clock phase
• Eight LVCMOS outputs distributed across two independently controllable banks
• Supports 1x and 2x multiplication ratios via address pins
• Low jitter performance with cycle-to-cycle jitter < 200 ps

Applications

• High-speed clock distribution systems
• Clock multiplication for processors and memory interfaces
• System testing modes requiring direct input clock drive

Part Context

The 2308-2HDCG belongs to the IDT 2308 family of zero-delay buffers. This specific suffix indicates a 2x multiplication capability variant packaged in a standard SOIC format. The component is part of Renesas' legacy data communications IC portfolio, characterized for commercial temperature ranges.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should verify compatibility with newer Renesas clock multiplier families or consult manufacturer resources for cross-reference data.
