23S09-1HPGGI

Overview

The Renesas Electronics 23S09-1HPGGI is a high-speed, low-phase-noise PLL-based zero-delay buffer designed for clock distribution. It accepts one reference input and drives nine low-skew outputs at frequencies up to 133 MHz using 3.3 V power. The device features an on-chip phase-locked loop that aligns the output phase with the input clock to achieve zero delay. It operates within a supply voltage range of 3 V to 3.6 V and is available in a 16-pin TSSOP package.

Feature Summary

• Zero-delay buffer architecture utilizing proprietary low-jitter PLL techniques
• Nine low-skew CMOS/LVTTL outputs driven from a single LVTTL reference input
• Operational frequency range up to 133 MHz at 3.3 V
• Low jitter performance with cycle-to-cycle jitter less than 200 ps

Applications

• High-speed clock distribution networks
• System synchronization requiring precise phase alignment
• Buffering reference clocks for multiple downstream components

Part Context

This component belongs to the IDT/Renesas 23S09 family of zero-delay buffers. It serves as a high-drive variant (indicated by the 'H' suffix) compared to standard drive versions, offering enhanced output capability while maintaining the same 1:9 distribution ratio and PLL-based functionality within the 16-pin form factor.

Replacement Considerations

The 23S09E-1HDCGI8 is listed as a discontinued part with the 23S09-1HPGGI identified as the manufacturer-recommended replacement. Verify pinout compatibility and electrical specifications against the specific datasheet revision before substitution.
