SY58608UMG

Clock Buffers, Drivers Overview

The SY58608UMG is a high-speed, fully differential 1:2 LVDS fanout buffer from Microchip Technology. It operates on a 2.5V ±5% supply and supports data rates up to 3.2 Gbps or clock frequencies up to 2 GHz. The device features guaranteed AC performance with propagation delays under 300 ps and within-device skew below 20 ps. It includes an integrated fail-safe input (FSI) to prevent output oscillation during invalid input states and delivers ultra-low jitter with typical additive phase jitter of 130 fs RMS.

Clock Buffers, Drivers Feature Summary

• Precision 1:2 LVDS Fanout Buffer with <20 ps within-device skew
• Fail-Safe Input (FSI) prevents output oscillation when input signal amplitude drops below threshold
• Ultra-low jitter design with 130 fs RMS typical additive phase jitter
• Internal 50Ω termination for IN/IN pins allows direct interface to LVPECL, LVDS, or CML signals

Clock Buffers, Drivers Applications

• SONET Clock And Data Distribution
• Fibre Channel Clock And Data Distribution
• Gigabit Ethernet Clock And Data Distribution
• Backplane Distribution

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and temperature range. The 'MG' suffix indicates a QFN-16 package with industrial temperature range (-40°C to +85°C). Confirm whether the required quantity corresponds to tube or reel packaging options available for this part number.

Clock Buffers, Drivers Selection Notes

Select the SY58608UMG for applications requiring low-skew distribution of high-speed differential signals. Ensure the power supply is regulated to 2.5V ±5%. Verify that the input signal swing meets the minimum requirements for the Fail-Safe Input feature if DC coupling is used without external termination networks.

Clock Buffers, Drivers Part Context

The SY58608U belongs to Microchip’s Precision Edge product line, designed for high-speed timing applications. It serves as a fanout buffer to replicate a single differential input into two identical outputs while maintaining signal integrity and minimizing jitter in high-frequency data transmission systems.
