23S09-1HDCGI

Overview

The Renesas Electronics 23S09-1HDCGI is a zero-delay clock buffer IC designed for high-speed clock distribution. It accepts one reference input and drives nine outputs, achieving a 1:9 ratio. The device operates within a supply voltage range of 3V to 3.6V and supports frequencies up to 200MHz. It utilizes an internal phase-locked loop (PLL) to align the output clock phase with the input reference, ensuring zero delay. The component is housed in a 16-SOIC package and is characterized for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Zero-delay operation using on-chip PLL to synchronize output phase with input reference
• Distributes one input clock to nine low-skew CMOS/LVTTL outputs
• Operates at frequencies up to 200MHz with 3V to 3.6V power supply
• Industrial temperature rating spanning -40°C to +85°C

Applications

• High-speed clock distribution networks requiring precise phase alignment
• System synchronization where zero propagation delay between input and output is critical
• Digital signal processing systems utilizing LVTTL/CMOS logic interfaces

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C). Confirm the package code 'DCG' corresponds to the 16-SOIC form factor. Check current manufacturing status as related variants may have end-of-life notices. Ensure compatibility with 3.3V logic levels for both input and output requirements.

Selection Notes

Select this component when a single clock source must drive multiple loads with minimal skew and zero latency relative to the input. Compare against standard buffers if phase alignment is not required. Verify that the 200MHz maximum frequency meets system timing constraints. Ensure the 16-SOIC footprint fits the PCB layout design.

Part Context

This part belongs to the IDT/Renesas 23S09 family of zero-delay buffers. It serves as a high-performance alternative to standard clock drivers by eliminating jitter accumulation through PLL feedback. The device is often used in conjunction with other clock generators or synthesizers to fan-out signals across complex digital systems.

Replacement Considerations

Public records indicate the 23S09E-1HDCGI8 variant has reached End-of-Life status. The manufacturer recommends the 23S09-1HPGGI8 as a replacement. Verify pinout and electrical specifications match before substitution.
