580G-01ILFT

Overview

The Renesas Electronics Corporation 580G-01ILFT is a glitch-free clock multiplexer IC designed for high-performance signal distribution. It operates within a supply voltage range of 2.5V to 5V and supports frequencies up to 270 MHz. The device features a 2:2 input-to-output configuration, ensuring seamless switching between clock sources without output glitches. It is housed in a 16-TSSOP package with dimensions of 0.173 inches (4.40mm) width. The component functions as a buffer, multiplexer, and divider, suitable for applications requiring reliable clock management across various digital systems.

Feature Summary

• Glitch-free switching capability ensures continuous clock signal integrity during source transitions
• Integrated buffer, multiplexer, and divider functions consolidate multiple timing roles into a single component
• Supports standard core voltages including 2.5V, 3.3V, and 5V for broad system compatibility

Applications

• High-speed data acquisition systems requiring precise clock synchronization
• Telecommunications equipment needing reliable signal distribution
• Industrial control systems utilizing multiple clock sources

Procurement Notes

Verify the specific suffix ILFT against official Renesas documentation to confirm lead-free status and tape-and-reel packaging specifications. Cross-reference the part number with current discontinuance notices or product change notifications, as clock generator families frequently undergo lifecycle updates. Ensure the 16-TSSOP footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution for glitch-free clock multiplexing and buffering is required. The 270 MHz maximum frequency supports most standard digital interface requirements. Consider the 16-TSSOP package size for space-constrained designs. Validate that the 2:2 topology aligns with the system's input/output clock architecture needs.

Part Context

The 580G series belongs to Renesas' ClockBlocks family of clock generators and distributors. This specific model integrates multiplexer and buffer functionalities, distinguishing it from simple fanout buffers. It addresses the need for clean clock switching in complex digital environments where signal integrity is critical for system stability and performance.

Replacement Considerations

Consult official Renesas substitution guides for direct equivalents. Verify pin-out compatibility and electrical characteristics if considering alternative clock multiplexers from other manufacturers.
