23S09E-1HPGGI8

Overview

The Renesas 23S09E-1HPGGI8 is a Zero Delay Buffer IC designed for high-speed clock distribution. It operates within a frequency range of up to 200MHz and accepts LVTTL input signals, providing CMOS and LVTTL outputs. The device functions on a single 3V to 3.6V supply voltage and features a 1:9 input-to-output ratio. It is housed in a 16-SOIC package with a width of 3.90mm. The component supports an industrial operating temperature range from -40°C to 85°C and includes an internal Phase-Locked Loop (PLL) with bypass capability.

Feature Summary

• Zero Delay Buffer architecture aligns output phase with the incoming clock reference.
• Supports frequencies up to 200MHz with LVTTL input and CMOS/LVTTL outputs.
• Integrated PLL with bypass functionality eliminates external RC networks.
• Available in a 16-SOIC surface-mount package suitable for industrial temperatures.

Applications

• High-speed clock distribution in digital systems.
• Clock buffering for processors and memory interfaces.
• Low-skew clock generation in communication equipment.

Procurement Notes

This specific part number is obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of current stock levels through authorized distributors is required, as availability is limited to existing inventory. Procurement planning should account for the discontinuation status and potential supply constraints associated with end-of-life components.

Selection Notes

Designers requiring this component should consider the recommended replacement, IDT23S09-1HPGGI8, which offers similar zero-delay buffer functionality. Selection criteria must include verifying pin compatibility, ensuring the replacement meets the required 200MHz frequency specifications, and confirming that the TSSOP package variant of the substitute fits the target PCB footprint if SOIC is not strictly mandated.

Part Context

The 23S09 series belongs to Renesas' portfolio of high-speed PLL-based clock buffers. This family addresses applications requiring low jitter and precise clock alignment. The 'E' suffix typically denotes specific manufacturing or revision codes within the broader 23S09 product line, which also includes variants like the 23S09A and different drive strength options such as the -1H series.

Replacement Considerations

Renesas recommends the IDT23S09-1HPGGI8 as the direct replacement. Note that the substitute utilizes a 16-TSSOP package rather than the original 16-SOIC form factor. Designers must verify mechanical clearance and soldering profile compatibility when transitioning from SOIC to TSSOP packaging.
