23S08E-2HDCGI8

Overview

The Renesas Electronics Corporation 23S08E-2HDCGI8 is a Zero Delay Buffer IC designed for clock distribution applications. It operates with a supply voltage of 3V to 3.6V and supports input frequencies up to 200MHz. The device features one input and nine outputs, packaged in a 16-SOIC format with a width of 3.90mm. It utilizes LVTTL input and CMOS/LVTTL output types. The component is characterized for industrial temperature ranges from -40°C to 85°C. This specific variant is marked as obsolete and no longer manufactured by the producer.

Feature Summary

• Zero Delay Buffer architecture synchronizing output phase to input clock
• Supports input frequencies up to 200MHz with 1:9 ratio
• Operates on single 3V to 3.6V power supply
• Industrial temperature range capability (-40°C to 85°C)

Applications

• High-speed clock distribution systems
• Phase-locked loop clock synchronization
• Digital signal processing clocking

Procurement Notes

This component is officially listed as obsolete and no longer manufactured. Availability is limited to existing stock from distributors or secondary markets. Verification of part authenticity and condition is critical when sourcing from non-direct channels. Designers should consider alternative components for new production runs due to end-of-life status.

Selection Notes

Select this part only for legacy system maintenance or replacement where pin compatibility is required. Verify that the 16-SOIC package dimensions (3.90mm width) fit the PCB footprint. Ensure the design accommodates the LVTTL input and CMOS/LVTTL output voltage levels. Confirm that the 200MHz maximum frequency meets the system timing requirements.

Part Context

The 23S08E-2HDCGI8 belongs to the IDT 23S08 family of zero delay buffers originally developed by Integrated Device Technology, now part of Renesas Electronics. These devices are designed to eliminate clock skew by feeding back the output clock to the PLL input. The 'E' suffix typically denotes an extended temperature range variant compared to commercial versions.

Replacement Considerations

Renesas recommends the 23S09-1HPGGI8 as a manufacturer-recommended substitute. Users should verify pinout compatibility and electrical specifications before swapping components. Other compatible parts may exist within the broader 23S08/23S09 family depending on specific I/O count and package requirements.
