23S09E-1HPGG

Overview

The Renesas 23S09E-1HPGG is a zero-delay clock buffer IC designed for high-speed clock distribution. It accepts one reference input and drives two banks of outputs (five and four) with low skew characteristics. The device operates within a frequency range of 10MHz to 133MHz at a supply voltage of 3V to 3.6V. It features an on-chip phase-locked loop (PLL) that aligns the phase between the incoming clock and output clocks, achieving zero delay. The component is housed in a 16-pin TSSOP package and supports spread spectrum input compatibility.

Feature Summary

• Zero-delay operation via on-chip PLL feedback from CLKOUT pad
• Distributes one input to two output banks (5+4) with <250ps skew
• Spread spectrum compatible input support
• Low cycle-to-cycle jitter (<200ps) and low power consumption

Applications

• High-speed clock distribution in data communications systems
• Clock buffering for processors and memory interfaces
• Systems requiring low-skew multi-point clocking

Part Context

The 23S09 series belongs to Renesas' family of zero-delay buffers, derived from earlier ICS designs. The -1H suffix indicates a high-drive version with faster rise and fall times compared to standard drive variants. This specific model utilizes the TSSOP package format, distinguishing it from SOIC-based counterparts in the same electrical family.

Replacement Considerations

Public documentation confirms the MFR recommended replacement for the obsolete 23S09E-1HDCGI8 is the 23S09-1HPGGI8. Verify pinout and package compatibility when substituting.
