23S05E-1DCGI8

Overview

The Renesas 23S05E-1DCGI8 is a 3.3V zero-delay clock buffer designed for high-speed digital systems. It utilizes a Phase-Locked Loop (PLL) to generate outputs with minimal input-to-output delay, ensuring precise timing alignment. The device supports frequencies from 10 MHz to 133 MHz and provides five LVCMOS outputs. Key electrical parameters include a maximum propagation delay of 0 ps, an output skew of less than 250 ps, and a core operating voltage of 3.3 V. It operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Feature Summary

• Zero-delay PLL architecture eliminates input-to-output propagation delay
• Low skew performance with <250 ps output skew between channels
• Supports clock frequencies from 10 MHz to 133 MHz
• Five LVCMOS outputs with 25 mA drive capability at TTL levels

Applications

• High-speed data acquisition systems requiring precise clock synchronization
• Digital signal processing (DSP) boards needing low-jitter clock distribution
• Telecommunications equipment utilizing multi-channel clocking architectures
• Industrial control systems demanding reliable timing under variable temperatures

Procurement Notes

Verify the specific suffix 'E' against official Renesas documentation, as standard listings often reference the 23S05-1HDCGI8 or 23S05-1DCGI8 variants. Confirm that the 'E' designation does not imply a restricted automotive qualification or a distinct pinout if it differs from the commercial grade. Ensure the SOIC-8 package dimensions match the required PCB footprint before ordering.

Selection Notes

Select this component when zero input-to-output delay is critical for system timing integrity. It is suitable for applications requiring fan-out of a single reference clock to multiple synchronous devices. Compare the 250 ps inter-output skew against system tolerance limits. Consider the 3.3V supply requirement and ensure compatibility with downstream LVCMOS logic levels.

Part Context

This part belongs to the IDT/Renesas 23S05 family of zero-delay buffers. These devices are engineered to replace crystal oscillators by buffering a lower-frequency reference clock while maintaining phase coherence. The 23S05 series is widely used in networking and computing infrastructure where jitter reduction and skew minimization are paramount for data integrity.

Replacement Considerations

The 23S05-1HDCGI8 is a documented equivalent within the same family, offering similar zero-delay functionality. Verify if the 'H' variant's higher drive strength is necessary for the specific load conditions. Cross-reference pinouts to ensure direct replacement compatibility without schematic modifications.
