SY100EL91LZC

Translators, Level Shifters Overview

The SY100EL91LZC is a triple LVPECL-to-ECL or LVPECL-to-LVECL translator manufactured by Microchip Technology. It operates with a VCC supply of 3.0V to 3.8V and supports VEE voltages ranging from -4.2V to -5.5V for ECL mode, or -3.0V to -3.8V for LVECL mode. The device features a propagation delay of 620ps typical at +25°C (differential) and output rise/fall times of 400ps typical. It is housed in a 20-pin wide SOIC package.

Translators, Level Shifters Feature Summary

• Provides three independent channels for translating LVPECL signals to either standard ECL or Low Voltage ECL levels.
• Includes a dedicated PECL_VBB pin that outputs a reference voltage suitable for interfacing with single-ended PECL inputs.
• Utilizes a fully differential design architecture to maintain signal integrity across the translation process.

Translators, Level Shifters Applications

• Translating LVPECL clock signals to ECL-compatible logic levels
• Interfacing LVPECL sources with LVECL destination circuits
• Converting single-ended PECL signals using the internal reference voltage

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'ZC' against official documentation to confirm it denotes the commercial temperature range and Sn-Pb lead finish. Confirm current availability status as this component may be subject to discontinuation or limited production runs. Ensure compatibility with existing PCB footprints for the 20-pin wide SOIC package before procurement.

Translators, Level Shifters Selection Notes

Select this component when multiple LVPECL signals require simultaneous translation to ECL or LVECL domains within a single integrated circuit. Consider the power supply requirements carefully, as the device necessitates distinct positive and negative rails. Evaluate the thermal environment to ensure operation remains within the specified commercial temperature limits.

Translators, Level Shifters Part Context

This part belongs to the SY100EL91L series of high-speed level translators. It is designed for applications requiring precise timing and low skew between multiple translated channels. The device integrates necessary biasing and reference generation internally to simplify the interface circuitry for mixed-voltage logic systems.

Translators, Level Shifters FAQ

How should the PECL_VBB pin be utilized?

The PECL_VBB pin provides an internal reference voltage output. It should be connected to the D input when converting single-ended PECL signals, and must be bypassed to ground via a 0.01 µF capacitor.

What are the valid power supply configurations?

The device requires VCC between 3.0V and 3.8V. For ECL mode, VEE ranges from -4.2V to -5.5V. For LVECL mode, VEE ranges from -3.0V to -3.8V.
