AD9122SCPZ-EP-RL

Overview

The AD9122SCPZ-EP-RL is a dual-channel, 16-bit high dynamic range digital-to-analog converter (DAC) from Analog Devices. It operates at a maximum sample rate of 1130 MSPS and supports multicarrier generation up to the Nyquist frequency. The device features an integrated complex modulator with 1x/2×/4×/8× interpolation options, allowing flexible carrier placement within the DAC bandwidth. It includes programmable gain, DC offset, and phase adjustment for sideband suppression. The analog output current is adjustable between 8.7 mA and 31.7 mA. Designed for direct conversion transmit applications, it utilizes a flexible LVDS interface and a 4-wire serial port for internal parameter programming.

Feature Summary

• Enhanced product qualification supporting defense and aerospace applications under AQEC standards
• Military temperature range operation from −55°C to +105°C
• Integrated 1x/2×/4×/8× interpolator and complex modulator for arbitrary carrier placement
• Flexible LVDS digital interface supporting word, byte, or nibble load modes

Applications

• Wireless infrastructure including W-CDMA, CDMA2000, TD-SCDMA, WiMAX, GSM, and LTE
• Digital high or low intermediate frequency (IF) synthesis
• Transmit diversity systems
• Wideband communications such as LMDS/MMDS and point-to-point links

Procurement Notes

Verify that the component meets the specific environmental requirements for military temperature ranges (-55°C to +105°C). Confirm the package type is the 72-lead Lead Frame Chip Scale Package (CP-72-7). Ensure the ordering suffix corresponds to the reel packaging format if required by automated assembly processes. Check for RoHS compliance status indicated by the 'Z' suffix in the part number.

Selection Notes

Select this model when enhanced reliability and controlled manufacturing baselines are required for defense or aerospace projects. The -EP designation indicates adherence to AQEC standards with single assembly and fabrication sites. Consider the 1130 MSPS maximum sample rate and 16-bit resolution for wideband signal synthesis needs. Evaluate power consumption specifications, which vary based on interpolation mode and operating frequency, against system thermal constraints.

Part Context

This component belongs to the AD9122-EP Enhanced Product family, specifically designed for ruggedized environments. It shares core functional specifications with the standard AD9122 but differs in manufacturing controls and environmental ratings. The -RL suffix denotes tape and reel packaging, distinguishing it from tray-packaged variants like the AD9122SCPZ-EP.

Replacement Considerations

The AD9122SCPZ-EP serves as the tray-packaged equivalent for manual handling or prototyping. For non-enhanced commercial applications requiring identical electrical performance without military qualification, the standard AD9122BCPZ may be considered, provided environmental tolerances align with the design.
