SY100EL91LZG

Translators, Level Shifters Overview

The SY100EL91LZG 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 and is housed in a 20-pin SOIC package.

Translators, Level Shifters Feature Summary

• Provides three independent channels for translating LVPECL signals to either standard ECL or Low Voltage ECL (LVECL) logic levels.
• Includes a dedicated PECL_VBB output pin designed to serve as the switching reference voltage when interfacing with single-ended LVPECL inputs.
• Utilizes a fully differential internal design architecture to maintain signal integrity across the translation process.

Translators, Level Shifters Applications

• Interfacing high-speed LVPECL clock sources with downstream ECL-based processing circuits
• Level translation between mixed-voltage logic domains in telecommunications equipment
• Signal routing in systems requiring conversion from low voltage positive emitter coupled logic to legacy ECL standards

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the required lead finish and temperature range. Confirm whether the tape and reel option is necessary for automated assembly processes. Ensure compatibility with existing PCB footprints for the 20-pin wide SOIC package before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when simultaneous translation of multiple LVPECL signals to ECL or LVECL domains is required within a single integrated circuit. Consider the power supply requirements carefully, as distinct rails are needed for the input and output sections to achieve proper level shifting functionality.

Translators, Level Shifters Part Context

Translators, Level Shifters FAQ

How should the PECL_VBB pin be utilized?

The PECL_VBB pin provides a reference voltage output intended for use when connecting single-ended LVPECL signals to the D inputs. It must be bypassed to ground via a capacitor.

What are the valid power supply configurations?

The device requires VCC connected to the positive supply (3.0V to 3.8V) and VEE connected to the negative supply. For ECL mode, VEE ranges from -4.2V to -5.5V; for LVECL mode, it ranges from -3.0V to -3.8V.
