23S05-1DCGI

Overview

The Renesas 23S05-1DCGI is a clock buffer IC featuring spread spectrum capabilities, designed for 3.3V operation. It provides five LVCMOS outputs with a maximum frequency of 133 MHz and zero propagation delay. The device operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-SOIC package. Key electrical parameters include a supply voltage range of 2.3 V to 2.7 V, a maximum power dissipation of 700 mW, and a typical operating current of 32 mA.

Feature Summary

• Spread spectrum clock buffering functionality
• Five LVCMOS outputs with 133 MHz maximum frequency
• Zero propagation delay (0 ps max)
• Industrial temperature range (-40°C to +85°C)

Applications

• Clock distribution in high-speed digital systems
• Spread spectrum clock generation for EMI reduction
• Embedded system timing networks

Procurement Notes

Verify component status as the 23S05-1DCGI is listed as obsolete or discontinued in available records. Confirm availability through authorized distributors or surplus channels. Ensure compatibility with existing design specifications before procurement, as replacement components may require schematic adjustments.

Selection Notes

Select this component for applications requiring spread spectrum clocking at 3.3V logic levels. Compare against the active 2305-1HDCGI8 if spread spectrum is not required, noting differences in drive strength and input/output configurations. Verify package compatibility with the 8-SOIC footprint.

Part Context

This part belongs to the Renesas 23S05 series of clock buffers. It shares the SOIC-8 package and basic zero-delay architecture with the 2305 series but adds spread spectrum modulation. The 'I' suffix indicates the industrial temperature grade, while 'G' denotes lead-free packaging.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source data. Consider the IDT23S05T-1DCGI alias or consult manufacturer documentation for direct replacements.
