SY10EPT28LZG

Translators, Level Shifters Overview

The SY10EPT28LZG is a differential LVPECL-to-LVTTL translator and LVTTL-to-differential LVPECL translator. It operates on a single +3.3V ±10% power supply, eliminating the need for negative voltage rails. The device supports maximum frequencies exceeding 275MHz for LVTTL outputs and 700MHz for LVPECL toggling. Propagation delays are less than 600ps for LVTTL-to-LVPECL conversion and under 2ns for LVPECL-to-LVTTL translation. It features internal 75kΩ input pull-down resistors and functions within an industrial temperature range of –40°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides bidirectional signal translation between Low Voltage PECL (LVPECL) differential levels and Low Voltage TTL (LVTTL) logic levels.
• Operates exclusively on a positive 3.3V power supply, removing the requirement for negative voltage generation circuits.
• Integrates internal 75kΩ input pull-down resistors to simplify interface design and reduce external component count.

Translators, Level Shifters Applications

• Backplane signal transmission and reception where mixed logic families are present
• Interfacing high-speed LVPECL sources with standard LVTTL destination inputs
• Converting LVTTL control signals to differential LVPECL drivers for noise immunity

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the required package type and lead finish. Confirm RoHS compliance status if restricted substances are a constraint. Ensure the operating temperature range aligns with the intended environmental conditions. Check for any specific handling requirements related to moisture sensitivity classification before assembly.

Translators, Level Shifters Selection Notes

Select this component when a compact solution is needed to bridge LVPECL and LVTTL domains without requiring dual power supplies. Consider the propagation delay specifications relative to system timing budgets. Evaluate the thermal resistance characteristics against the expected PCB airflow and ambient temperature constraints.
