SY58036UMG-TR

Clock Buffers, Drivers Overview

The SY58036UMG-TR is a high-speed 1:6 fanout buffer with an integrated 2:1 multiplexer input, manufactured by Microchip Technology (originally Micrel). It operates on a 2.5V or 3.3V supply and supports clock frequencies up to 7 GHz. The device features ultra-low skew outputs of less than 20 ps and typical RMS phase jitter of 50 fs. It provides six 400 mV LVPECL output pairs with propagation delays under 300 ps. The unique input architecture accepts AC- or DC-coupled differential signals as small as 100 mV without external termination networks.

Clock Buffers, Drivers Feature Summary

• 1:6 Fanout Buffer with 2:1 MUX Input for redundant clock switchover
• Ultra-low skew (<20 ps) and low jitter (50 fs RMS typical)
• Operates at 2.5V ±5% or 3.3V ±10% with frequency range DC to >6 GHz
• Unique 3-pin input termination accepts CML, PECL, and LVDS inputs

Clock Buffers, Drivers Applications

• Redundant clock distribution systems
• SONET/SDH clock distribution
• Fibre Channel distribution
• Gigabit Ethernet clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the manufacturer origin, as the datasheet identifies Micrel, Inc., which was acquired by Microchip Technology. Confirm that the MLF-32 package includes the exposed pad soldered to ground for thermal management. Ensure the ordering suffix matches the required lead finish (NiPdAu for Pb-Free versions). Check humidity sensitivity levels and storage requirements due to the dry-packaging mentioned in the documentation.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:6 fanout buffer with integrated mux capability is required for frequencies exceeding 6 GHz. Compare with SY58034U if CML outputs are needed instead of LVPECL. Compare with SY58035U if 800mV LVPECL swing is preferred over the standard 400mV swing. Ensure the design accommodates the specific input termination requirements using the VT pins for maximum interface flexibility.

Clock Buffers, Drivers Part Context

This part belongs to the Precision Edge product line from Micrel/Microchip, designed for high-speed clock distribution. It is functionally similar to the SY58035U but offers lower output swing (400mV vs 800mV LVPECL). The SY58036U is distinct from the SY58034U, which provides CML outputs rather than LVPECL. It serves as a critical component in high-bandwidth telecommunications and data communication infrastructure.

Clock Buffers, Drivers Replacement Considerations

SY58035UMG-TR: Offers 800mV LVPECL outputs instead of 400mV. SY58034UMG-TR: Provides CML outputs instead of LVPECL. Verify pin compatibility and output voltage levels before substitution.
