9LRS3197AKLF

Overview

The Renesas Electronics 9LRS3197AKLF is a fixed-frequency clock generator designed for PC main clock applications. It operates within a supply voltage range of 1.8V to 3V and supports an operating temperature range of 0°C to 70°C. The component is housed in a 32-pin VFQFPN package with dimensions of 5mm x 5mm x 1mm, featuring an exposed pad. It is classified as a lead-free plastic device compliant with RoHS standards.

Feature Summary

• Fixed frequency output optimized for PC main clock generation
• Single-ended LVCMOS output configuration
• Low power consumption suitable for portable systems
• Lead-free packaging with RoHS compliance

Applications

• Personal computer motherboard clock distribution
• Consumer electronics requiring stable system timing
• Industrial control systems with standard voltage requirements

Procurement Notes

Verify the manufacturer origin, as IDT was acquired by Renesas. Confirm the specific suffix 'KLF' matches the required tape-and-reel or tray quantity (490 per tray) and moisture sensitivity level (MSL 3). Ensure the ordering part number aligns with current Renesas nomenclature to avoid discrepancies in datasheet references.

Selection Notes

Select this component when a fixed-frequency clock source is required for legacy or standard PC architectures. It is suitable for designs needing a single-ended output without PLL jitter attenuation capabilities. Verify that the 1.8V to 3V supply range matches the target system's voltage rails and that the 32-VFQFPN footprint fits the PCB layout constraints.

Part Context

This component belongs to the 9LRS3197 series, originally developed by Integrated Device Technology (IDT) before its acquisition by Renesas Electronics. The series is categorized under application-specific clock and timing solutions, specifically targeting the personal computer market for main system clock generation tasks.

Replacement Considerations

Check for direct cross-reference numbers from Renesas or IDT distributors. Generic clock generators may require external components or different pinouts. Verify if newer revisions of the 9LRS3197 series offer improved electrical characteristics or updated packaging options.
