SY100EL91ZC-TR

Translators, Level Shifters Overview

The SY100EL91ZC-TR is a triple PECL-to-ECL translator manufactured by Microchip Technology. It operates with a VCC supply of 4.75V to 5.25V and a VEE supply of -4.2V to -5.5V. The device features a typical propagation delay of 620ps, with a maximum of 800ps for single-ended inputs at +85°C. It utilizes a 20-pin wide SOIC package (Z20-1) and supports commercial temperature ranges from 0°C to +70°C.

Translators, Level Shifters Feature Summary

• Translates standard voltage PECL signals to different ECL output signals
• Includes a dedicated PECL reference voltage output for interfacing with single-ended inputs
• Provides fully differential design architecture

Translators, Level Shifters Applications

• Interfacing between PECL and ECL logic families
• Voltage level translation in high-speed digital systems
• Single-ended PECL signal conversion using the VBB reference pin

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence or limited availability. Confirm that the specific ZC suffix corresponds to the commercial temperature range required for your application environment. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Translators, Level Shifters Selection Notes

Select this component when translating three independent PECL channels to ECL levels within a compact footprint. Consider the requirement for separate power rails for VCC and VEE during system design. Evaluate the need for the VBB reference pin if single-ended input configurations are utilized in the target circuit topology.

Translators, Level Shifters Part Context

This device belongs to the SY100EL91 series of translators produced by Micrel, now part of Microchip Technology. It is designed for applications requiring reliable interface between different high-speed logic families. The ZC suffix indicates the commercial operating temperature range variant housed in a leaded 20-pin SOIC package.

Translators, Level Shifters FAQ

How should the PECL_VBB pin be used?

The PECL_VBB pin provides a reference voltage for interfacing with single-ended PECL signals. It should be connected to the D input when using single-ended inputs and bypassed to ground via a 0.01 µF capacitor.

What are the power supply requirements?

The device requires three power connections: VCC connected to the positive supply (4.75V to 5.25V), VEE connected to the negative supply (-4.2V to -5.5V), and GND pins connected to the system ground plane.
