SY58033UMG

Clock Buffers, Drivers Overview

The SY58033UMG is a Precision Edge ultra-precision 1:8 fanout buffer featuring 400mV LVPECL outputs and internal termination. It operates from a 2.5V ±5% or 3.3V ±10% supply within the industrial temperature range of –40°C to +85°C. The device supports clock frequencies up to 5.5GHz with a typical propagation delay of 200ps (max 280ps) and output rise/fall times under 80ps. It delivers low-jitter performance with 76fs RMS phase jitter (12kHz–20MHz) and guarantees less than 20ps skew between outputs.

Clock Buffers, Drivers Feature Summary

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix for packaging configuration. The 'MG' suffix indicates a QFN-32 package in tube form, while 'TR' denotes tape and reel. Confirm RoHS compliance status and moisture sensitivity level requirements before procurement to ensure compatibility with assembly processes.

Clock Buffers, Drivers Selection Notes

Select the SY58033UMG when an 8-channel LVPECL fanout buffer is required with minimal skew and jitter. Ensure the design accommodates the 32-pin QFN package dimensions and thermal requirements. Verify that the input signal levels match the supported differential swings for LVPECL, CML, or LVDS sources.

Clock Buffers, Drivers Part Context

The SY58033U belongs to Micrel’s Precision Edge product line, designed for high-speed, fully differential applications. It complements other devices like the SY58031U (CML outputs) and SY58032U (800mV LVPECL outputs), offering a specialized solution for low-swing LVPECL clock distribution networks.

Clock Buffers, Drivers Replacement Considerations

Direct functional replacements include the SY58031U for CML outputs and the SY58032U for 800mV LVPECL outputs. Cross-reference pinouts and electrical characteristics carefully, as output swing and input interface requirements differ between these variants.
