MAX9311ECJ+

Clock Buffers, Drivers Overview

The MAX9311ECJ+ is a low-skew, 1-to-10 differential driver designed for clock and data distribution. It features a 2:1 multiplexer to select between two differential inputs (CLK0/CLK1), which are then reproduced at ten differential outputs. The device supports differential HSTL and LVPECL operation with a supply range of +2.25V to +3.8V, and LVECL operation from -2.25V to -3.8V. Key electrical parameters include a maximum switching frequency of 3 GHz, typical part-to-part skew of 30 ps, and output-to-output skew of 12 ps. It is housed in a 32-pin LQFP package.

Clock Buffers, Drivers Feature Summary

• Supports differential HSTL/LVPECL (+2.25V to +3.8V) and LVECL (-2.25V to -3.8V) supplies
• Features 2:1 input multiplexing with 10 differential outputs
• Provides low skew performance with 30ps part-to-part and 12ps output-to-output typical values
• Includes on-chip VBB reference output for single-ended input adaptation

Clock Buffers, Drivers Applications

• Precision clock distribution across backplanes or boards
• Low-jitter data repeater systems
• High-speed digital signal routing requiring differential signaling

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'ECJ' corresponds to the 32-pin LQFP (7mm x 7mm) package and the -40°C to +85°C temperature range. Confirm that the component is sourced as a new product rather than a surplus item, as availability may vary. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Clock Buffers, Drivers Selection Notes

Select the MAX9311ECJ+ when a 1-to-10 fanout buffer with low skew is required for HSTL, LVPECL, or LVECL interfaces. Choose this model over the MAX9313 if the specific VBB reference voltage offset (1.425V below VCC vs 1.32V) aligns with the system design requirements. Ensure the PCB layout accommodates the 32-LQFP footprint and allows for proper bypassing near the VCC pins.

Clock Buffers, Drivers Part Context

This component belongs to the MAX9311/MAX9313 family of 1:10 differential drivers manufactured by Analog Devices Inc./Maxim Integrated. The ECJ suffix specifically denotes the 32-pin LQFP package variant within this series. These devices are engineered for high-performance clock distribution applications where signal integrity and timing precision are critical constraints.

Clock Buffers, Drivers Replacement Considerations

The datasheet indicates pin compatibility with the MC100LVEP111 for the MAX9311 function. Verify that any substitute component matches the 32-LQFP package dimensions and maintains equivalent skew specifications for direct replacement in existing designs.
