AD9639BCPZRL-170

Analog To Digital Converters (ADC) Overview

The AD9639BCPZRL-170 is a quad, 12-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 170 MSPS. It features four independent channels with JESD204B compliant serial outputs and an on-chip phase-locked loop (PLL). The device utilizes a single 1.8 V supply and incorporates a pipeline architecture with a 780 MHz full-power analog bandwidth. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 64.5 dBFS at 84.3 MHz input frequency, Differential Nonlinearity (DNL) of ±0.28 LSB, and Integral Nonlinearity (INL) of ±0.45 LSB. Total power dissipation is approximately 1.139 W to 1.215 W depending on the specific grade, with standby power consumption typically around 152 mW per channel.

Analog To Digital Converters (ADC) Feature Summary

• Features a clock duty cycle stabilizer to maintain performance across varying clock inputs.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete ordering code against the manufacturer's current datasheet revision. Confirm that the RL suffix corresponds to the required reel packaging specification for your assembly line. Ensure the BCPZ variant meets RoHS compliance requirements for your target market. Cross-reference the specific speed grade (170 MSPS vs 210 MSPS) to guarantee system timing compatibility.

Analog To Digital Converters (ADC) Selection Notes

Select this component when multi-channel digitization is required within strict spatial constraints. The integrated PLL simplifies clock distribution by eliminating external multiplier circuits. Evaluate the 1.8 V single-supply operation against available power rails. Consider the JESD204 interface complexity if interfacing with FPGAs lacking native support, as digital logic must handle the serialization protocol.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9639 family of high-speed, low-power quad ADCs from Analog Devices. It shares architectural similarities with the AD9239 but differs in output coding and maximum sampling rates. The device is designed for applications requiring dense channel counts and high dynamic range, serving as a direct replacement for older dual-channel solutions in modern RF front-ends.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Verify compatibility with existing PCB footprints and thermal management designs before considering alternative quad-channel ADCs from other manufacturers.
