23S05T-1DCGI8

Overview

The Renesas 23S05T-1DCGI8 is a clock buffer featuring spread spectrum capabilities, designed for low jitter applications. It operates with a supply voltage range of 2.3 V to 2.7 V and supports output frequencies up to 133 MHz. The device provides five LVCMOS outputs with a maximum propagation delay of 0 ps. Packaged in an SOIC-8 format, it functions within an industrial temperature range of -40°C to +85°C. Key electrical parameters include a typical operating current of 32 mA and a power dissipation rating of 700 mW.

Feature Summary

• Zero maximum propagation delay (0 ps)
• Five LVCMOS outputs supporting up to 133 MHz
• Industrial temperature range (-40°C to +85°C)

Applications

• Low jitter clock distribution systems
• Spread spectrum clock generation circuits
• High-speed digital interface synchronization

Procurement Notes

Verify component status as the base model 23S05T-1DCGI is listed as obsolete. Confirm availability of the specific 'I8' suffix variant through authorized channels. Check RoHS compliance details and ensure the package matches the required SOIC-8 footprint for PCB integration.

Selection Notes

Select this component when spread spectrum modulation is required alongside zero-delay buffering. Ensure the design accommodates the 2.3 V to 2.7 V supply voltage constraint. Verify that the 32 mA operating current fits within the system's thermal budget, considering the 700 mW power dissipation limit in the SOIC-8 package.

Part Context

This part belongs to the 23S05T series of clock buffers from Renesas Electronics. It shares architectural similarities with other members like the 2305 series but differs in its support for spread spectrum inputs and specific voltage ranges. The 'I8' suffix typically denotes industrial temperature grading and reel packaging.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider evaluating the 2305-1HDCGI8 for similar zero-delay buffering needs, noting differences in voltage range and spread spectrum capability.
