23S09-1HPGG

Overview

The Renesas Electronics Corporation 23S09-1HPGG is a high-speed phase-locked loop (PLL) clock buffer designed for zero-delay clock distribution applications. It accepts one reference input and drives nine low-skew outputs, operating within a frequency range of 10 MHz to 133 MHz at a supply voltage of 3 V to 3.6 V. The device features an on-chip PLL that locks to the input clock via the REF pin, with feedback obtained from the CLKOUT pad. Packaged in a 16-pin TSSOP, it provides high drive capability suitable for demanding clock distribution networks.

Feature Summary

• Zero-delay operation aligns output clock phase with the incoming reference clock
• Distributes one input signal to nine low-skew CMOS/LVTTL outputs
• On-chip PLL eliminates the need for external components
• High drive strength version (-1H suffix) supports frequencies up to 133 MHz

Applications

• High-speed clock distribution in networking equipment
• Clock buffering for system-on-chip (SoC) architectures
• Low-jitter clock generation for data converters

Part Context

The 23S09-1HPGG belongs to the 23S09 family of zero-delay buffers. It is functionally similar to the 23S05 but offers nine outputs instead of five. The -1H suffix indicates a high-drive variant with faster rise and fall times compared to standard versions, while the PGG suffix denotes the 16-pin TSSOP package type.

Replacement Considerations

The datasheet lists IDT23S09-1HPG8 as an alternative packaging option for the same functional device. Designers should verify package dimensions and moisture sensitivity levels when substituting between tube and tape-and-reel formats.
