23S09-1HDCG

Overview

The Renesas Electronics 23S09-1HDCG is a high-speed phase-locked loop (PLL) clock buffer designed for zero-delay clock distribution. It accepts one reference input and drives nine outputs across two banks of four low-skew clocks, with an additional output available via the CLKOUT pad for internal PLL feedback. The device operates within a frequency range of 10MHz to 133MHz using a single 3V to 3.6V power supply. Packaged in a 16-pin SOIC, it achieves zero delay by aligning the phase between the incoming clock and the output clock. In the absence of an input clock, the device enters a low-power shutdown mode.

Feature Summary

• Zero-delay operation achieved through on-chip PLL locking to the REF pin input
• Operates at frequencies up to 133MHz with higher drive capability than standard -1 variants
• Distributes one input clock to two banks of four low-skew outputs
• Low power consumption: less than 12μA in commercial shutdown mode

Applications

• High-speed clock distribution systems
• Digital signal processing equipment
• Telecommunications infrastructure

Procurement Notes

Verify RoHS compliance status as some distributors list this specific suffix under non-compliant categories. Confirm package dimensions against the 16-SOIC specification (0.154 inch width). Check moisture sensitivity level requirements for surface mount assembly processes. Ensure the -1H designation matches the required 133MHz performance threshold.

Selection Notes

Select this component when zero-phase alignment is critical for system timing. The -1H suffix indicates high-drive capability suitable for heavier capacitive loads compared to the standard -1 version. Ensure the operating environment stays within the 0°C to +70°C commercial temperature range. Verify that the LVTTL input logic levels are compatible with the source clock generator.

Part Context

This part belongs to the 23S09 family of zero-delay buffers, which are 16-pin versions of the 23S05. The 23S09-1HDCG specifically denotes the high-drive (-1H) variant in a tube-packaged SOIC-16 format. It serves as a direct replacement for legacy IDT parts with similar pinouts and electrical characteristics, maintaining compatibility with existing clock distribution architectures.

Replacement Considerations

The 23S09E-1HDCGI8 is listed as obsolete with the 23S09-1HPGGI8 recommended as the manufacturer-replaced alternative.
