23S09-1DCG

Overview

The Renesas Electronics 23S09-1DCG is a 3.3V zero-delay clock buffer featuring spread spectrum compatibility. It utilizes an internal phase-locked loop to distribute one reference input to nine outputs, organized into two banks of five and four. The device operates within a frequency range of 10MHz to 133MHz with output skew less than 250ps and cycle-to-cycle jitter under 200ps. Packaged in a 16-pin SOIC (0.154" width), it supports LVTTL/LVCMOS interfaces and functions at supply voltages between 3V and 3.6V.

Feature Summary

• Zero-delay PLL architecture aligns output phase with the incoming reference clock
• Spread spectrum compatible for EMI reduction without external RC networks
• Independent output enable controls for separate output banks
• Low power consumption with tri-state outputs during power-down mode

Applications

• High-speed clock distribution in networking equipment
• Server and storage system timing architectures
• Industrial control systems requiring low-skew clocking

Procurement Notes

Verify RoHS compliance status as documentation indicates variations across manufacturing dates. Confirm moisture sensitivity level (MSL) ratings prior to PCB assembly to ensure proper handling. Check for specific package width tolerances matching the 16-SOIC specification. Validate that the -1H suffix is not required if high drive strength is necessary for the application.

Selection Notes

Select this component when a single-ended LVTTL or LVCMOS input is required for up to nine loads. The standard drive version (-1) suits most general applications; choose the -1H variant only if faster rise/fall times are critical. Ensure the operating temperature range matches the commercial (0°C to 70°C) or industrial (-40°C to 85°C) requirements of the target system.

Part Context

This part belongs to the 23S09 family of high-speed PLL clock buffers. It serves as a 16-pin expansion of the 23S05, providing increased fan-out capability. The device integrates proprietary low-jitter PLL techniques to maintain signal integrity across high-frequency digital systems.

Replacement Considerations

The IDT2309-1HPGG is a documented alternative offering similar zero-delay buffering in a TSSOP package. Verify pinout compatibility and drive strength differences before substitution.
