AD9639BCPZ-170

Analog To Digital Converters (ADC) Overview

The AD9639BCPZ-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 JESD204 coded serial digital outputs and operates from a single 1.8 V supply. The device includes an on-chip temperature sensor and a high-speed serial interface supporting data rates up to 3.4 Gbps per channel. Key electrical specifications include a full-power analog bandwidth of 780 MHz, a typical signal-to-noise ratio (SNR) of 63.5 dB at 84.3 MHz input frequency, and differential nonlinearity (DNL) of ±0.28 LSB. Power dissipation is specified at 1.139 W total under standard conditions.

Analog To Digital Converters (ADC) Feature Summary

• Integrates four 12-bit ADCs within a compact 72-lead LFCSP package for space-constrained designs.
• Features an on-chip phase-locked loop (PLL) that multiplies the single external sampling clock to generate internal data rate clocks.
• Includes a clock duty cycle stabilizer to maintain performance across varying clock duty cycles without dynamic degradation.
• Supports flexible synchronization schemes and programmable pin functions via a serial port interface.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete ordering suffix against the manufacturer's current datasheet revision to ensure correct speed grade and package variant. Confirm RoHS compliance status and lead-free material declarations prior to procurement. Check for any specific environmental or reliability certifications required by the target application standards. Ensure compatibility with existing supply chain agreements and distributor authorization levels.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a quad-channel, high-speed digitization solution is required within a limited board area. Evaluate the 170 MSPS speed grade against system bandwidth requirements, noting the 780 MHz analog input bandwidth. Consider the power consumption profile relative to thermal management capabilities in the final enclosure. Verify that the JESD204 interface logic in the receiving FPGA or ASIC supports the required lane count and data rate configuration.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9639 family of high-performance, low-power, quad-channel ADCs from Analog Devices. The family shares identical architectural features and pinouts but differs primarily in maximum sampling speed grades. The BCPZ designation indicates a Pb-free/RoHS-compliant 72-lead Lead Frame Chip Scale Package (LFCSP). Other variants in the series support higher speeds such as 210 MSPS.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9639BCPZ-210 is a verified substitute offering identical functionality with a higher maximum sampling rate of 210 MSPS. No other direct pin-compatible replacements are documented in the official datasheet.
