580G-01LF

Overview

The Renesas Electronics Corporation 580G-01LF is a Glitch-Free Clock Multiplexer IC designed to switch between two clock sources without generating glitches or short pulses. It operates within a supply voltage range of 2.5V, 3.3V, and 5V, supporting input frequencies from 2 MHz to 270 MHz. The device is housed in a 16-TSSOP package with a pitch of 0.65 mm. This component belongs to the ClockBlocks family and functions as a buffer, multiplexer, and divider for clock distribution applications.

Feature Summary

• Glitch-free switching capability between dual clock sources
• Integrated buffer, multiplexer, and divider functions
• Supports wide input frequency range up to 270 MHz

Applications

• Clock source selection in embedded systems
• Signal integrity maintenance in high-speed digital circuits
• System reset synchronization logic

Procurement Notes

Verify component authenticity through authorized channels due to obsolete lifecycle status. Confirm package marking and datasheet revision against original specifications. Check for RoHS compliance documentation. Validate pinout compatibility before integration into existing PCB layouts. Ensure storage conditions meet moisture sensitivity level requirements.

Selection Notes

Select this component when glitch-free transition between two clock inputs is required. Consider the 270 MHz maximum input frequency limit for signal speed. Evaluate the 16-TSSOP package constraints for board space. Verify power supply voltage compatibility with system rails. Assess thermal performance within the specified operating temperature range.

Part Context

The 580G-01LF is part of the ICS580 series of clock multiplexers manufactured by Renesas Electronics. It serves as a specialized timing solution for systems requiring reliable clock source switching. The device integrates multiple clock management functions into a single compact package, reducing component count in complex digital designs.

Replacement Considerations

ICS580G-01LFT is a tape-and-reel variant of the same functional device. Verify package type differences if reel packaging is preferred over tube. Cross-reference with other glitch-free mux devices if specific pinout changes are acceptable.
