AD9239BCPZ-210

Overview

The AD9239BCPZ-210 is a quad, 12-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 210 MSPS. It features four independent channels with coded serial digital outputs including error correction codes. The device utilizes a single 1.8 V power supply and incorporates an on-chip temperature sensor. Key electrical specifications include a full-power analog bandwidth of 780 MHz, typical differential nonlinearity (DNL) of ±0.6 LSB, and integral nonlinearity (INL) of ±1.3 LSB. It supports LVPECL, LVDS, or CMOS clock inputs and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates four 12-bit ADCs in a compact package with high-speed serial output interfaces.
• Includes an on-chip phase-locked loop (PLL) for data rate multiplication and clock distribution.
• Features a duty cycle stabilizer to maintain performance across varying clock input duty cycles.
• Provides programmable pin functions and multiple power-down modes for flexible system control.

Applications

• Communication receivers
• Cable head end equipment and M-CMTS systems
• Broadband radios
• Wireless infrastructure transceivers
• Radar and military-aerospace subsystems

Procurement Notes

Verify the specific suffix '210' to confirm the 210 MSPS sampling rate variant, as the AD9239 family includes 170 MSPS and 250 MSPS options. Ensure the ordering information matches the required speed grade before procurement. Confirm RoHS compliance and lead-free status if required by assembly standards. Check for any specific environmental or handling restrictions noted in the latest datasheet revision.

Selection Notes

Select this component when a quad-channel, high-speed ADC with integrated serialization is required. The 210 MSPS speed offers a balance between the 170 MSPS and 250 MSPS variants. Consider the 780 MHz analog bandwidth and 1.8 V supply requirements. Evaluate the need for the internal PLL and duty cycle stabilizer against external clocking solutions. Verify that the LFCSP-72 package fits the PCB layout constraints.

Part Context

The AD9239BCPZ-210 belongs to the AD9239 family of quad, 12-bit ADCs from Analog Devices. This family shares the same core architecture and pinout but differs in maximum sampling rates: 170 MSPS, 210 MSPS, and 250 MSPS. All variants utilize a 72-lead LFCSP package and operate on a single 1.8 V supply. The BC part number indicates the commercial/industrial temperature range and specific performance binning.

Replacement Considerations

Direct replacements within the same package and functionality are the AD9239BCPZ-170 (lower speed) and AD9239BCPZ-250 (higher speed). These parts share identical pinouts and software compatibility. Ensure the system clock and timing requirements align with the selected speed variant's specifications.
