AD9239BCPZ-170

Overview

The AD9239BCPZ-170 is a quad, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 170 MSPS. It features four independent channels with serial output data rates up to 2.72 Gbps per channel. The device utilizes a single 1.8 V power supply and includes an on-chip temperature sensor. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 64.5 dBFS at an input frequency of 9.7 MHz and a full-power analog bandwidth of 780 MHz. Differential Nonlinearity (DNL) is typically ±0.6 LSB, while Integral Nonlinearity (INL) is typically ±0.9 LSB. The component is housed in a 72-lead LFCSP package and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates four 12-bit ADCs in a compact package to reduce board space.
• Features coded serial digital outputs with error correction code (ECC) per channel.
• Includes an on-chip PLL for clock distribution and multiplication.
• Contains an on-chip temperature sensor for monitoring.

Applications

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

Procurement Notes

Verify the specific suffix '170' to confirm the 170 MSPS sampling rate variant, as other variants like 210 or 250 exist. Ensure the LFCSP-72 package matches the design footprint. Confirm RoHS compliance status through official documentation before integration.

Selection Notes

Select this model when a quad-channel solution is required to minimize PCB area compared to dual-channel alternatives. Consider the 170 MSPS speed if system requirements do not necessitate higher throughput. Verify that the 1.8 V supply voltage aligns with the system power architecture.

Part Context

The AD9239 belongs to a family of high-speed, low-power quad ADCs designed for wide dynamic range applications. It shares architectural similarities with other ADI converters but distinguishes itself through its serialized packet output format and integrated error correction capabilities, facilitating easier interfacing with FPGA systems.
