SY58610UMG-TR

Signal Switches, Multiplexers, Decoders Overview

The SY58610UMG-TR is a high-speed, fully differential LVPECL 2:1 multiplexer from Microchip Technology's Precision Edge line. It processes clock signals up to 2.5GHz and data patterns up to 3.2Gbps with less than 10ps peak-to-peak total jitter. The device operates on a single supply of 2.5V ±5% or 3.3V ±10%. It features internal termination for LVPECL, LVDS, or CML inputs as small as 100mV without external resistors. Outputs provide 800mV LVPECL swings with rise/fall times under 130ps. It includes fail-safe input logic and is housed in a 16-pin QFN package.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'TR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the industrial temperature range (-40°C to +85°C) aligns with the operational environment specifications. Ensure compatibility with the 16-VFQFN (3x3mm) footprint and exposed pad grounding requirements during PCB layout and procurement planning.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when precise 800mV LVPECL outputs are required for buffering selected differential inputs. It is suitable for designs needing direct interface with LVDS or CML sources without level-shifting networks. Consider alternatives like the SY58609U or SY58611U if lower output swings such as CML or LVDS are preferred instead of standard LVPECL levels.

Signal Switches, Multiplexers, Decoders FAQ

How does the Fail Safe Input function operate?

The Fail Safe Input latches the outputs to their last valid state if the input signal amplitude drops below approximately 100mVpk, preventing metastable conditions or oscillation.

What input signal types are supported without external components?

The device accepts LVPECL, LVDS, or CML differential signals, either AC- or DC-coupled, with swings as small as 100mV without requiring external level-shifting or termination resistor networks.
