Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'I' indicates the industrial temperature grade (-40°C to +85°C). Confirm that the '-TR' suffix denotes tape and reel packaging. Ensure compatibility with existing PCB layouts designed for the 20-pin TSSOP form factor before finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a fully differential 4:1 multiplexer is required for high-frequency applications up to 3GHz. It serves as a pin-for-pin replacement for the MC10/100EP57DT. Consider its internal pull-down resistors and VBB reference capabilities for simplified termination schemes in PECL or ECL logic environments.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the ECL Pro™ family of high-speed timing and distribution devices. Originally developed by Micrel, Inc., the product line was acquired by Microchip Technology. The SY100EP57V series is designed for precision edge timing applications requiring robust differential signal integrity.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The SY100EP57VK4I-TR is a direct pin-for-pin, plug-in replacement for the MC100EP57DT and MC100EP57DTR2.

Signal Switches, Multiplexers, Decoders FAQ

What is the function of the VBB pins?

The VBB pins provide an output reference voltage, typically equal to VCC minus 1.4V. They are used to bias unused inverting inputs for single-ended applications or serve as termination points for AC-coupled differential inputs.

How does the device handle floating select inputs?

The SEL0 and SEL1 pins include internal 75kΩ pull-down resistors. If left floating, the default condition for these pins is LOW.
