MAX9322ECY+D

Clock Buffers, Drivers Overview

The MAX9322ECY+D is a low-skew, 1:15 differential clock driver manufactured by Analog Devices Inc./Maxim Integrated. It reproduces or divides one of two differential input clocks to 15 differential outputs at frequencies exceeding 1.0 GHz. The device supports LVPECL operation with a +2.375V to +3.8V supply and LVECL operation with a -2.375V to -3.8V supply. Key electrical parameters include a maximum added random jitter of 1.2ps RMS at 1.0GHz, a propagation delay of 900ps typical, and an output-to-output skew of 56ps typical. It operates within a temperature range of -40°C to +85°C and is housed in a 52-TQFP package.

Clock Buffers, Drivers Feature Summary

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'ECY' corresponds to the 52-pin TQFP package variant as listed in the manufacturer's ordering information. Confirm that the component meets the required industrial temperature range specifications for the target application environment before integration.

Clock Buffers, Drivers Selection Notes

Select this component when a high-fanout differential clock distribution solution is required with minimal skew. Ensure the system power supply aligns with either the positive LVPECL or negative LVECL voltage rails. Consider the thermal dissipation requirements of the 52-TQFP package if operating near the upper temperature limits.

Clock Buffers, Drivers Part Context

This device belongs to the Maxim Integrated family of high-performance clock drivers designed for demanding digital systems. It serves as a critical interface for distributing reference clocks across complex backplanes and multi-chip modules where signal integrity and timing precision are paramount.

Clock Buffers, Drivers Replacement Considerations

For 1:10 clock distribution requirements, refer to the MAX9311 or MAX9313 datasheets. For 1:5 configurations, consult the MAX9316 data sheet. Verify pinout and electrical compatibility before substituting with other manufacturers' parts.
