23S09-1DCGI8

Overview

The Renesas Electronics 23S09-1DCGI8 is a high-speed phase-locked loop (PLL) clock buffer designed for zero-delay clock distribution. It accepts one reference input and drives nine low-skew outputs, operating within a frequency range of 10MHz to 133MHz. The device utilizes an on-chip PLL that locks to the input clock via the REF pin, with feedback obtained from the CLKOUT pad. It functions in a 16-pin SOIC package, supporting power-down modes with tri-stated outputs when no input clock is present.

Feature Summary

• Zero-delay buffer architecture aligning output phase with incoming clock
• 1:9 input-to-output ratio driving two banks of four low-skew clocks
• Operational frequency range from 10MHz to 133MHz
• On-chip PLL with internal feedback path

Applications

• High-speed clock distribution networks
• System synchronization requiring zero delay
• Low skew clock buffering for digital circuits

Part Context

This component belongs to the 23S09 series of PLL-based clock buffers. It serves as a 16-pin variant derived from the 23S05 family, specifically engineered to handle higher drive requirements compared to standard versions. The -1 designation indicates operation up to 133MHz with enhanced drive capabilities.
