SY56034ARMG-TR

Analog Switches - Special Purpose Overview

The SY56034ARMG-TR is a fully differential, low voltage CML 2:6 (2+4) multiplexer with crosspoint capability. It processes clock signals up to 5GHz or data patterns up to 6.4Gbps. The device operates from a 2.5V ±5% core supply and a 1.2V/1.8V/2.5V ±5% output supply. It features an internal 3-pin input termination architecture that accepts LVPECL, LVDS, or CML signals as small as 100mV without external level-shifting. Outputs are 400mV CML with rise/fall times less than 80ps. It is housed in a 32-pin QFN package and operates over the industrial temperature range of –40°C to +85°C.

Analog Switches - Special Purpose Procurement Notes

Verify the component origin, as the datasheet identifies Micrel, Inc. as the manufacturer. Microchip Technology acquired Micrel; confirm if the specific ordering suffix indicates current Microchip production status or legacy stock. Ensure the package marking matches the official documentation. Check RoHS compliance details against the latest regulatory requirements for your region before finalizing procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when a high-speed differential multiplexer with crosspoint functionality is required. It supports multiple supply voltages for inputs and outputs, allowing flexibility in system design. Verify that the application requires CML signaling and fits within the specified frequency limits. Consider the 32-pin QFN package constraints and thermal management needs for the industrial temperature range during board layout.

Analog Switches - Special Purpose FAQ

How does the device handle AC-coupled input interfaces?

For AC-coupled inputs, an internal high impedance resistor divider biases the VT pin. Users should bypass the VT pin with a 0.1µF low ESR capacitor to VCC to provide the necessary bias voltage.

What is the maximum allowable input voltage swing?

The device accepts differential signals as small as 100mV (200mVpp). The absolute maximum input voltage swing ranges from 0.1V to 1.0V single-ended, or 0.2V to 2.0V differential.

Can unused output pairs be left floating?

No, unused output pairs must be terminated properly. Specifically, when VCCO is 1.2V, unused outputs must not be left floating to ensure proper driver operation.
