SY100E417JC

Translators, Level Shifters Overview

The SY100E417JC is a quint LVPECL-to-PECL translator manufactured by Microchip Technology, housed in a 28-pin PLCC package. It supports both PECL-to-LVPECL and LVPECL-to-PECL translation modes using three power rails: VCC (5.0V), VCCO (3.3V or 5.0V), and VCC_VBB (3.3V or 5.0V). Propagation delay ranges from 410ps to 610ps for differential inputs and 380ps to 680ps for single-ended inputs. The device operates within a commercial temperature range of 0°C to 70°C.

Translators, Level Shifters Feature Summary

• Provides five independent channels for translating between LVPECL and PECL signal levels.
• Supports dual-directional translation for both LVPECL-to-PECL and PECL-to-LVPECL applications.
• Features fully differential design with internal biasing for stable operation under open input conditions.
• Includes a dedicated VBB output pin to interface single-ended input signals.

Translators, Level Shifters Applications

• Translating standard PECL signals to differential LVPECL outputs.
• Converting differential LVPECL signals to PECL outputs.
• Acting as a differential line receiver for PECL-to-PECL or LVPECL-to-LVPECL signaling.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix to confirm the package type and lead finish. The 'JC' suffix indicates a commercial temperature grade and Sn-Pb finish. Confirm that the component meets RoHS requirements if applicable, noting that Pb-Free variants use the 'JY' suffix. Ensure the supply chain source provides valid traceability documentation for this legacy part.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems requiring level translation between 3.3V LVPECL and 5.0V PECL standards. Ensure the design accommodates the requirement for three distinct power supplies (VCC, VCCO, VCC_VBB) based on the chosen translation direction. Verify that the 28-pin PLCC package fits the PCB layout constraints and that the propagation delay specifications meet the system timing requirements.

Translators, Level Shifters Part Context

This device belongs to the SY100E series of high-speed ECL translators. It was originally developed by Micrel, Inc., which was later acquired by Microchip Technology. The component is designed for high-performance digital systems requiring reliable voltage level shifting between different ECL logic families.

Translators, Level Shifters FAQ

What are the required power supply voltages for PECL-to-LVPECL translation?

For PECL-to-LVPECL translation, VCC and VCC_VBB must be connected to 5.0V, while VCCO must be connected to 3.3V.

How should the VBB pin be handled for single-ended inputs?

When using single-ended inputs, connect the VBB output to the Dn input and bypass the VBB pin to VCC via a 0.01 µF capacitor to act as a switching reference.
