SY58026UMI-TR

Signal Switches, Multiplexers, Decoders Overview

The SY58026UMI-TR is a dual 2:1 multiplexer featuring two independent differential MUXs with guaranteed AC performance over temperature and voltage. It supports data rates exceeding 5Gbps with propagation delays under 310ps and rise/fall times below 110ps. The device incorporates unique input isolation to minimize crosstalk and ultra-low jitter characteristics, including less than 1ps RMS random jitter. It accepts DC-coupled and AC-coupled inputs via a VT pin that provides access to internal 50-ohm termination networks. Outputs provide an 800mV LVPECL swing, operating from a 2.5V or 3.3V supply within the industrial temperature range of -40°C to +85°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and lead finish. The 'UMI' designation indicates the MLF-32 package with Sn-Pb lead finish, while 'UMG' denotes Pb-free NiPdAu finish. Confirm moisture sensitivity classification and dry-packaging requirements prior to assembly. Ensure compatibility with the intended power supply voltage and temperature range specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing systems requiring dual differential multiplexing with integrated input termination. It is suitable for applications needing low jitter performance and support for multiple input logic standards like CML and LVDS. Consider the MLF-32 package constraints and thermal management requirements for the exposed pad. Verify that the 800mV LVPECL output swing aligns with downstream receiver input thresholds.
