23S09-1HDCGI8

Overview

The Renesas 23S09-1HDCGI8 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 features an on-chip PLL that locks to the input clock on the REF pin, with feedback obtained from the CLKOUT pad. It operates on a single 3V to 3.6V power supply and is housed in a 16-pin SOIC package. In the absence of an input clock, the device enters a low-power power-down mode.

Feature Summary

• Zero-delay buffer architecture aligns output clock phase with the incoming reference clock.
• Drives nine low-skew outputs from a single reference input.
• Operates at frequencies up to 133MHz with 3.3V supply voltage.
• Includes power-down mode with less than 25μA current consumption when no input clock is present.

Applications

• High-speed clock distribution systems
• System-on-chip (SoC) clocking solutions
• Digital signal processing (DSP) clock networks

Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm tape-and-reel packaging and industrial temperature grade (-40°C to 85°C). Cross-reference part numbers such as IDT23S09-1HDCGI8 or 23S09E-1HDCGI8 to ensure compatibility with existing bill of materials, noting potential status changes like obsolescence for related variants.

Selection Notes

Select this component for applications requiring precise phase alignment between input and multiple output clocks without external feedback components. Ensure the design supports the 10MHz to 133MHz operational range. Verify that the 16-SOIC package dimensions fit the PCB layout constraints and that the 3V to 3.6V supply rail is stable within the specified tolerance.

Part Context

This part belongs to the 23S09 family of zero-delay buffers. It is functionally similar to the 23S05 but provides nine outputs instead of five. The '-1H' designation indicates a high-drive version with faster rise and fall times compared to standard variants. Related parts include the 2309 series, which offers similar functionality with potentially different drive strengths or packaging options.

Replacement Considerations

Publicly confirmed substitutes include the IDT23S09-1HDCGI8, which shares identical electrical characteristics and pinout. Users should verify if the 'E' suffix variant (23S09E-1HDCGI8) is available, though some sources indicate it may be obsolete. Always check manufacturer PCNs for any recent assembly facility or label changes.
