280GLFT

Overview

The Renesas 280GLFT is a VersaClock clock and frequency synthesizer integrated circuit manufactured by Renesas Electronics Corporation. It functions as a fanout distribution buffer and spread spectrum clock generator with a maximum operating frequency of 200MHz. The device features a single circuit configuration with a 1:4 input-to-output ratio, accepting clock or crystal inputs and providing CMOS outputs. It operates within a supply voltage range of 3.135V to 3.465V and supports an industrial temperature range of 0°C to 70°C. The component is housed in a 16-TSSOP package.

Feature Summary

• Integrated spread spectrum clock generation capability for EMI reduction
• Supports both clock signal and crystal oscillator inputs
• Provides four CMOS outputs from a single input source
• Operates on a standard 3.3V power supply (3.135V–3.465V)

Applications

• General purpose clock distribution in embedded systems
• Fanout buffering for high-speed digital logic interfaces
• Spread spectrum clocking in consumer electronics

Procurement Notes

The 280GLFT is classified as a discontinued product with an End-of-Life date recorded as March 30, 2025. Verification of current availability requires checking distributor stock levels, as the part is no longer in active production. Buyers should confirm the specific suffix 'LF' indicates lead-free compliance and verify the package type matches design requirements before procurement.

Selection Notes

Select the 280GLFT when a low-pin-count solution is required for distributing a single clock signal to four destinations. Ensure the application utilizes CMOS-compatible inputs and outputs. The 16-TSSOP package limits pin count compared to larger buffers; verify that the 200MHz frequency limit meets system timing requirements. Consider the 1:4 ratio constraint if more outputs are needed.

Part Context

This component belongs to the VersaClock family of timing solutions from Renesas. It serves as a simplified alternative to programmable PLL synthesizers, focusing on deterministic fanout and basic jitter management. The base model number is 280PG, with the GLFT suffix denoting the specific package, lead-free status, and tape-and-reel packaging format.

Replacement Considerations

Publicly confirmed substitute part numbers for the 280GLFT were not found in the provided documentation. Due to the discontinued status, engineers must evaluate functional equivalents based on pin compatibility and electrical specifications.
