SY100EL91ZI

Translators, Level Shifters Overview

The SY100EL91ZI is a triple PECL-to-ECL translator manufactured by Microchip Technology, housed in a 20-pin wide SOIC package. 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 for differential inputs and 620ps for single-ended inputs. It supports an operating temperature range from -40°C to +85°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
• Features a fully differential design architecture

Translators, Level Shifters Applications

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 industrial temperature rating (-40°C to +85°C) matches your system requirements. Ensure proper bypassing of VCC and VEE pins with 0.01µF capacitors during implementation to maintain signal integrity.

Translators, Level Shifters Selection Notes

Select this component when translating PECL signals to ECL levels within the specified voltage ranges. Consider the 20-pin SOIC package constraints and the need for separate power rails for VCC and VEE. Verify that the 620ps typical propagation delay meets your timing requirements for the target application environment.

Translators, Level Shifters Part Context

This component belongs to the SY100EL91 series of translators. It was originally developed by Micrel, Inc., which has since been acquired by Microchip Technology. The datasheet indicates it is not recommended for new designs, suggesting potential availability limitations or newer alternatives in the manufacturer's portfolio.

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. When used, it should be connected to the D input and bypassed to ground via a 0.01µF capacitor.

What are the power supply requirements?

The device requires three power connections: VCC (4.75V to 5.25V), VEE (-4.2V to -5.5V), and GND. Both VCC and VEE must be bypassed to ground with 0.01µF capacitors.
