SY58603UMG-TR

Clock Buffers, Drivers Overview

The SY58603UMG-TR is a high-speed, fully differential CML buffer from the Precision Edge product line. It processes clock signals up to 2.5GHz or data patterns up to 4.25Gbps with less than 10pspp total jitter. The device operates on a 2.5V ±5% or 3.3V ±10% supply and features an internal 3-pin input termination architecture for LVPECL, LVDS, or CML inputs. Key electrical parameters include a propagation delay of 150–350ps, output rise/fall times under 85ps, and a typical output voltage swing of 400mV.

Clock Buffers, Drivers Feature Summary

• Ultra-low jitter design: <1ps RMS cycle-to-cycle jitter and <10ps PP total jitter
• Fail Safe Input (FSI) prevents output oscillation when input signals are invalid or below threshold
• Integrated 3-pin input termination allows direct interfacing with LVPECL, LVDS, or CML signals without external resistors
• Guaranteed AC performance over temperature and voltage with throughput exceeding 4.25Gbps

Clock Buffers, Drivers Applications

• Data Distribution: OC-48, OC-48+FEC, XAUI
• Backplane Buffering
• SONET clock or data distribution
• Fibre Channel clock or data distribution
• Gigabit Ethernet clock or data distribution

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the Tape and Reel packaging format as specified in the datasheet. Confirm the package type is DFN-8 and the operating range is Industrial (-40°C to +85°C). Ensure compatibility with 2.5V or 3.3V power supplies before procurement.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring low jitter buffering of CML signals. If LVPECL outputs are required instead, consider the SY58604U. For LVDS outputs, consider the SY58605U. This part is suitable for storage, ATE, test and measurement, enterprise networking, and high-end server markets.

Clock Buffers, Drivers Part Context

The SY58603U is part of Micrel’s high-speed Precision Edge product line. Micrel was acquired by Microchip Technology, which now manufactures and distributes this series. The device is designed for high-performance clock distribution and data buffering in telecommunications and computing infrastructure.

Clock Buffers, Drivers Replacement Considerations

For LVPECL output requirements, the SY58604U is a compatible alternative within the same family. For LVDS output requirements, the SY58605U serves as a functional substitute. Both share similar input architectures and operational characteristics.
