951462AGLFT

Application Specific Clock/Timing Overview

The Renesas Electronics Corporation 951462AGLFT is a clock synthesizer and jitter cleaner designed for PC main clock applications. It features 20 outputs with a maximum output frequency of 280 MHz, driven by a maximum input frequency of 14.318 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V and consumes approximately 400 mA of operating current. Packaged in a TSSOP-64 surface-mount format, it supports an industrial temperature range from 0°C to +70°C. This component serves as a critical timing solution for generating stable clock signals in computer systems.

Application Specific Clock/Timing Feature Summary

• Supports maximum output frequencies up to 280 MHz
• Accepts crystal inputs with a maximum frequency of 14.318 MHz
• Operates on a single 3.3V power supply (3.135V–3.465V)

Application Specific Clock/Timing Applications

• PC main clock generation
• System timing distribution
• Computer motherboard clocking

Application Specific Clock/Timing Procurement Notes

The 951462AGLF variant is listed as obsolete or end-of-life by the manufacturer. While the 951462AGLFT suffix indicates tape-and-reel packaging, availability is limited due to the product's discontinued status. Buyers should verify current stock levels with authorized distributors and consider alternative components for new designs. Lead times and minimum order quantities vary by supplier inventory.

Application Specific Clock/Timing Selection Notes

Select this component when a high-output-count clock synthesizer is required for legacy PC architectures. Ensure the design accommodates the specific 3.3V supply tolerance and 400 mA current draw. Verify that the TSSOP-64 package footprint matches the PCB layout. For new designs, evaluate modern replacements as this part is no longer actively promoted.

Application Specific Clock/Timing Part Context

This part belongs to the ICS951462A family of clock synthesizers. The 'GLF' suffix denotes lead-free RoHS compliance, while 'T' indicates tube packaging for the base part; however, distributor listings often associate 'T' at the end with reel options for similar SKUs. It is distinct from buffer-only devices, offering synthesis capabilities for multiple system clocks.

Application Specific Clock/Timing Replacement Considerations

As the 951462AGLF is obsolete, check for direct pin-compatible upgrades within the Renesas portfolio. Evaluate newer clock generators with similar output counts and PCIe/PCI compatibility if applicable.
