AD9643BCPZ-210

Analog To Digital Converters (ADC) Overview

The AD9643BCPZ-210 is a dual, 14-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 210 MSPS. It features a multistage differential pipelined architecture with integrated output error correction logic and an internal voltage reference. The device supports flexible analog input ranges from 1.4 V p-p to 2.0 V p-p and utilizes LVDS outputs compliant with ANSI-644 levels. Powered by single 1.8 V supplies for both analog and digital sections, it includes an integer 1-to-8 clock divider, a duty cycle stabilizer, and serial port control via SPI. The component is housed in a 64-lead LFCSP package and operates within the industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix corresponds to the required 210 MSPS performance tier before procurement. Confirm that the LFCSP-64 package thermal requirements are met through proper PCB ground plane connection. Ensure compatibility with existing system interfaces regarding LVDS signaling and SPI control protocols.

Analog To Digital Converters (ADC) Selection Notes

Select this variant when a sampling rate between 170 MSPS and 250 MSPS is required but the highest speed grade is unnecessary. Consider the pin compatibility with the AD9613, AD6649, and AD6643 if migration from other converters is planned. Evaluate the total power consumption against system thermal constraints given the 1.8 V supply requirement.

Analog To Digital Converters (ADC) Part Context

The AD9643 series comprises three speed grades: 170 MSPS, 210 MSPS, and 250 MSPS. All variants share identical pinouts, architectural features, and functional block diagrams. The primary distinction lies in the guaranteed maximum conversion rate and associated AC performance specifications such as SNR and SFDR at higher frequencies.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible replacements include the AD9643-170 and AD9643-250 for different speed requirements. The AD9613 offers a 12-bit alternative with identical pinout. The AD6649 and AD6643 are also listed as pin-compatible options within the same family.
