SY58016LMI

Overview

The SY58016LMI is a high-speed, current mode logic (CML) differential receiver manufactured by Micrel. It supports data rates up to 10.7Gbps and operates from DC. The device features internal 50Ω input termination and internal 50Ω output load resistors, allowing direct interfacing with CML logic signals without external components. It accepts CML or PECL differential inputs and provides CML compatible outputs. Powered by a nominal +3.3V supply, it includes gain of at least 4V/V and maintains an edge rate of less than 45ps.

Feature Summary

• Accepts CML/PECL differential inputs with integrated 50Ω pull-up resistors for simplified interface design
• Provides CML differential outputs with built-in 50Ω load resistors to eliminate external termination requirements
• Operates as a line receiver, driver, or limiting amplifier with gain greater than or equal to 4V/V
• Supports high-speed signal integrity with propagation delay under 150ps and low jitter characteristics

Applications

• Backplane buffering systems
• OC-3/OC-192 SONET clock or data distribution
• Gigabit Ethernet (GigE) clock or data distribution
• Fibre Channel distribution networks

Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. The 'MI' designation typically corresponds to the MLF-16 package in industrial temperature ranges. Confirm that the source document explicitly links this suffix to the physical package dimensions and marking codes provided in the ordering information table. Ensure compatibility with existing board layouts requiring the 3mm x 3mm footprint.

Selection Notes

Select this component when internal termination is required to reduce board space and component count. It is suitable for applications needing direct CML interfacing without external resistors. Consider the 3.3V supply requirement and the MLF-16 package thermal characteristics. Verify that the input swing requirements meet the minimum 100mVp-p specification for guaranteed AC performance at maximum data rates.

Part Context

This device belongs to the SY58016L family of high-speed differential receivers. It is designed for telecommunications and high-speed digital interfaces where signal integrity and speed are critical. The family includes die versions and packaged variants, offering flexibility for different manufacturing processes. It serves as a key component in maintaining signal quality across backplanes and optical networking equipment.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult official Microchip/Micrel resources for cross-reference lists. Ensure any replacement matches the CML interface, voltage levels, and package dimensions. Verify that the alternative device supports the required 10Gbps data rate and internal termination specifications.
