23S09-1HPGG8

Overview

The Renesas 23S09-1HPGG8 is a zero-delay clock buffer IC designed for high-speed clock distribution applications. It operates within a frequency range of 10MHz to 133MHz and accepts a single LVCMOS input, distributing the signal to nine outputs across two banks. The device features an on-chip phase-locked loop (PLL) that aligns the output clock phase with the reference input, achieving zero delay without external components. It supports spread spectrum inputs and provides low jitter performance with cycle-to-cycle jitter less than 200ps and output skew under 250ps. The unit is housed in a 16-TSSOP package and functions at a supply voltage of 3V to 3.6V.

Feature Summary

• Zero-delay PLL architecture aligns output phase with input reference
• Distributes one input to nine outputs with independent bank enable controls
• Spread spectrum compatible for EMI reduction
• Low jitter (<200ps c-c) and low skew (<250ps) performance

Applications

• High-speed clock distribution in digital systems
• Jitter cleaning and phase alignment for data converters
• Clock buffering for FPGAs and ASICs

Procurement Notes

Verify component status as the IDT23S09-1HPG8 variant is listed as obsolete by distributors. Confirm availability of the specific 23S09-1HPGG8 suffix through authorized channels. Check for moisture sensitivity level (MSL 1) handling requirements during storage and assembly. Ensure RoHS compliance status matches current manufacturing specifications.

Selection Notes

Select this model for applications requiring a 1:9 fan-out ratio with zero-delay characteristics. The -1H suffix indicates higher drive strength compared to standard variants, suitable for heavier loads. Ensure the operating temperature range meets system requirements, typically 0°C to 70°C for commercial versions. Verify that the 16-TSSOP package dimensions fit the PCB layout constraints.

Part Context

This component belongs to the 23S09 family of zero-delay buffers from Renesas Electronics. It serves as a high-speed clock distributor, often replacing discrete buffer solutions to reduce board space and improve signal integrity. The device integrates the PLL feedback path internally, simplifying design complexity compared to earlier generations.

Replacement Considerations

The IDT23S09-1HPG8 is identified as an obsolete alternative. Direct pin-compatible replacements within the same family should be verified against the latest datasheet for electrical parameter equivalence.
