23S09-1HDCG8

Overview

The Renesas Electronics 23S09-1HDCG8 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 at 3.3V VDD. The device features separate output enables for two output banks, ensuring flexible signal management. It utilizes an on-chip PLL with feedback obtained from the CLKOUT pad, eliminating the need for external RC networks. The component is housed in a 16-pin SOIC package and supports spread spectrum compatibility.

Feature Summary

• Zero-delay buffer architecture aligns output phase with incoming clock
• Distributes one input to nine outputs across two banks
• Low jitter performance with cycle-to-cycle jitter less than 200ps
• Output skew specification under 250ps

Applications

• High-speed clock distribution systems
• Spread spectrum clock generation applications
• System synchronization requiring low skew outputs

Part Context

This component belongs to the 23S09 series of zero-delay buffers. The '1' suffix indicates the standard drive version, while 'H' denotes high drive capability with faster rise and fall times. The 'CG' suffix specifies the commercial temperature range and SOIC package type. This part is a 16-pin variant derived from the 23S05 family, optimized for 3.3V operation.
