23S05-1DCGI8

Overview

The Renesas 23S05-1DCGI8 is a zero-delay clock buffer designed for high-speed digital systems. It operates on a single 3.3V supply and supports input frequencies from 10 MHz to 133 MHz. The device features one LVCMOS input and five LVCMOS outputs, providing low-skew signal distribution with a maximum output skew of 250 ps. It utilizes an internal PLL to achieve zero propagation delay between the input and output clocks. The component is housed in an 8-pin SOIC package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Zero-delay buffering using internal PLL technology
• Five LVCMOS outputs with <250 ps skew
• Supports input frequencies up to 133 MHz
• Industrial temperature range (-40°C to +85°C)
• Spread spectrum compatible

Applications

• High-speed data acquisition systems
• Telecommunications equipment clock distribution
• Network infrastructure timing synchronization
• Industrial control system clocking

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and '8' indicates the tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accounts for the 3.3V core voltage requirements and appropriate decoupling strategies for the PLL circuitry.

Selection Notes

Select this component when zero propagation delay is critical for system timing integrity. It is suitable for applications requiring a single input to drive multiple synchronous loads with minimal skew. Compare against the standard 2305 series if spread spectrum functionality is not required or if commercial temperature ranges are sufficient for the application environment.

Part Context

This part belongs to the 23S05 family of zero-delay buffers, which are specialized for low-jitter clock distribution. It serves as a successor or variant within the broader IDT/Renesas clock buffer portfolio, offering enhanced features such as spread spectrum compatibility compared to earlier non-s variants. The device integrates the feedback loop internally to simplify board layout.

Replacement Considerations

Direct substitutes include the 2305-1DCGI8 for non-spread spectrum applications. Verify pinout compatibility and electrical specifications before swapping. Alternative families may require level shifting or additional external components due to differences in PLL architecture or output drive capabilities.
