AD9512UCPZ-EP

Clock Buffers, Drivers Overview

The AD9512UCPZ-EP is a 1.2 GHz clock distribution integrated circuit designed for defense and aerospace applications under the AQEC standard. It features two differential 1.6 GHz inputs and five programmable outputs: three LVPECL (up to 1.2 GHz) and two selectable LVDS/CMOS (up to 800 MHz/250 MHz). Each output includes integer dividers from 1 to 32 with phase adjustment capabilities. The device operates on a single 3.3 V supply within an extended military temperature range of −55°C to +85°C, housed in a 48-lead LFCSP package.

Clock Buffers, Drivers Feature Summary

• Military-grade reliability supporting defense and aerospace applications per AQEC standards
• Five independent outputs with programmable integer dividers (1–32) and phase select
• Low additive jitter performance: 225 fs rms for LVPECL and 275 fs rms for CMOS/LVDS
• Extended operating temperature range from −55°C to +85°C

Clock Buffers, Drivers Applications

• Clocking high-speed ADCs, DACs, DDSs, DDCs, and DUCs
• Defense and aerospace systems requiring controlled manufacturing baselines
• Low jitter, low phase noise clock distribution networks

Clock Buffers, Drivers Procurement Notes

Verify that the specific ordering suffix matches the required packaging format. Confirm that the enhanced product designation aligns with project requirements for controlled manufacturing baselines and qualification data availability. Ensure compatibility with the specified 48-lead LFCSP footprint during PCB layout.

Clock Buffers, Drivers Selection Notes

Select this component when subpicosecond jitter performance is critical for maximizing data converter accuracy. Note that unlike the standard AD9512, this EP version does not support the delay block element in Channel 4. Verify that the serial control interface and power supply constraints fit the system design before integration.

Clock Buffers, Drivers Part Context

This part belongs to the AD9512-EP Enhanced Product family, specifically tailored for ruggedized environments. It shares the core functional architecture of the commercial AD9512 but adheres to stricter quality controls, including a single assembly site, single fabrication site, and enhanced change notification protocols defined by the AQEC standard.

Clock Buffers, Drivers Replacement Considerations

The standard AD9512BCPZ serves as the commercial equivalent but lacks the military temperature range and AQEC compliance. Substitution requires verifying that the absence of the Channel 4 delay block in the EP version does not impact timing requirements.
