SY58607UMG

Clock Buffers, Drivers Overview

The SY58607UMG is a high-speed, fully differential 1:2 LVPECL fanout buffer from Microchip Technology. It processes clock signals up to 2.5 GHz or data patterns up to 3.2 Gbps with guaranteed AC performance across the industrial temperature range of –40°C to +85°C. The device features an ultra-low jitter design with 41 fs additive phase jitter and less than 20 ps within-device skew. It operates on a 2.5V ±5% or 3.3V ±10% supply voltage and includes fail-safe input functionality to prevent output oscillation during invalid input conditions.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix for packaging requirements. The standard tube configuration contains 100 units per tube. Alternatively, the -TR suffix indicates a tape and reel configuration containing 1,000 units per reel. Confirm package availability directly with the manufacturer or authorized sales offices as distribution options may vary.

Clock Buffers, Drivers Selection Notes

Select the SY58607UMG for applications requiring 800 mV LVPECL outputs. For designs needing CML or LVDS outputs instead, consider the SY58606U (400 mV swing) or SY58608U (325 mV swing). Ensure the power supply matches the required 2.5V ±5% or 3.3V ±10% specifications to maintain the guaranteed electrical characteristics.

Clock Buffers, Drivers Part Context

The SY58607UMG belongs to Microchip’s Precision Edge® product line of high-speed logic devices. Originally developed by Micrel, this component was integrated into Microchip's portfolio following their acquisition. The part number designation 'U' indicates dual voltage support, while 'M' specifies the 16-lead QFN package.

Clock Buffers, Drivers Replacement Considerations

For alternative output swings within the same family, consider the SY58606U for 400 mV CML/LVDS outputs or the SY58608U for 325 mV LVDS outputs. These parts share similar form factors but differ in output voltage levels and interface compatibility.

Clock Buffers, Drivers FAQ

How does the Fail-Safe Input (FSI) function operate?

The FSI circuit senses the input signal amplitude. If the signal drops below approximately 100 mVpk (typically 30 mVpk), it latches the outputs to their last valid state, preventing metastability or oscillation.

What is the maximum frequency capability of the SY58607UMG?

The device supports data rates up to 3.2 Gbps (NRZ) and clock frequencies up to 2.5 GHz (with VOUT > 400 mV).

Can the SY58607UMG accept DC-coupled inputs?

Yes, the differential input accepts DC-coupled signals as small as 100 mV (200 mVpp) without requiring level-shifting or external termination resistor networks in the signal path.
