9112AF-17LF

Overview

The Renesas 9112AF-17LF is a clock buffer component designed for PC system applications. It features nine outputs and supports maximum input frequencies up to 133 MHz. The device operates within a supply voltage range of 4.5 V to 5.5 V, drawing a typical operating current of 45 mA. It is housed in a QSOP-16 surface-mount package and functions reliably across an industrial temperature range from 0°C to +70°C. This part belongs to the 9112-17 series and serves as a high-performance driver for distributing clock signals.

Feature Summary

• Nine output channels for clock distribution
• Maximum input frequency of 133 MHz
• QSOP-16 surface-mount packaging
• Operating temperature range of 0°C to +70°C

Applications

• PC system clock distribution
• High-speed digital circuit timing
• Clock signal buffering in computing hardware

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Availability is limited to existing stock or secondary market sources. Verify RoHS compliance details through official documentation before procurement. Ensure compatibility with legacy systems requiring this specific pinout and electrical specification.

Selection Notes

Select this part for designs requiring a 9-output clock buffer with 133 MHz capability. Confirm that the QSOP-16 package fits the PCB layout constraints. Verify that the 4.5V to 5.5V supply voltage aligns with the system power rails. Consider the thermal dissipation characteristics of the QSOP-16 package under continuous operation at maximum frequency.

Part Context

The 9112AF-17LF is part of the Renesas (formerly IDT) 9112 series of clock buffers. It is functionally similar to other variants like the 9112-26 but differs in package and specific electrical parameters. The 'LF' suffix typically indicates lead-free construction. It is distinct from Renesas power management ICs such as the ISL9112 series.

Replacement Considerations

Direct substitutes may include other 9-output clock buffers from Renesas or compatible manufacturers. Verify pin-to-pin compatibility and electrical specifications. Check for availability of newer generations if the obsolete status causes supply chain risks.
