23S05E-1HDCGI

Overview

The Renesas 23S05E-1HDCGI is a 3.3V Zero Delay Low Skew Buffer designed for high-speed clock distribution. It features one LVCMOS input and five LVCMOS outputs, operating within an input frequency range of 10 MHz to 133 MHz. The device maintains a core voltage of 3.3V with an output skew of 250 ps and peak-to-peak jitter of 200 ps. Packaged in an 8-pin SOIC (DCG8) with a pitch of 1.27 mm, it supports an industrial temperature range of -40°C to 85°C. This component ensures precise timing alignment without feedback inputs or programmable clock capabilities.

Feature Summary

• Zero delay buffering with low skew performance (250 ps output skew)
• Single LVCMOS input driving five LVCMOS outputs
• Operates at 3.3V core voltage with 10–133 MHz frequency range
• 8-pin SOIC package suitable for compact PCB layouts

Applications

• High-speed digital system clock distribution
• FPGA and ASIC clock synchronization
• Telecommunications equipment timing networks

Procurement Notes

Verify the specific suffix 'E' against official Renesas documentation to confirm if it denotes a specific tape-and-reel variant or environmental compliance level distinct from the base '2305-1HDCGI'. Confirm availability status as distributor data may vary. Ensure the 8-pin SOIC package matches the target footprint requirements.

Selection Notes

Select this buffer when zero-delay clock alignment is required for LVCMOS interfaces. The 1:5 fan-out capability suits applications needing to drive multiple synchronous loads from a single source. Verify that the 133 MHz maximum frequency meets the system clock requirements and that the 3.3V logic levels are compatible with downstream components.

Part Context

This component belongs to the Renesas 2305 series of zero-delay buffers. These devices are engineered to eliminate propagation delay between input and output clocks, making them critical for maintaining signal integrity in high-speed digital designs where timing skew must be minimized across multiple branches.

Replacement Considerations

The base part number 2305-1HDCGI serves as a direct functional equivalent. Verify pin compatibility and electrical specifications before substitution. No other public substitute part numbers are confirmed for this specific model.
