AD9642BCPZ-210

Analog To Digital Converters (ADC) Overview

The AD9642BCPZ-210 is a single-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a sampling rate of 210 MSPS. It utilizes a multistage differential pipelined architecture with integrated output error correction logic and an internal voltage reference. The device accepts differential analog inputs with a nominal input span of 1.75 V p-p and outputs data via DDR LVDS drivers compliant with ANSI-644 levels. Powered by a single 1.8 V supply for both analog and digital sections, it features a 3-wire SPI interface for configuration. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 71.5 dBFS at 185 MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 95 dBc under the same conditions.

Analog To Digital Converters (ADC) Feature Summary

• Multistage differential pipelined ADC core with integrated output error correction logic

Analog To Digital Converters (ADC) Applications

• Multimode digital receivers for 3G cellular infrastructure
• TD-SCDMA, WiMAX, WCDMA, CDMA2000, GSM, EDGE, and LTE systems
• I/Q demodulation and smart antenna systems
• Ultrasound equipment and broadband data applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix (-210) matches the required 210 MSPS conversion rate during procurement. Confirm that the LFCSP-32 package thermal requirements are met by the target PCB design, specifically ensuring the exposed paddle is soldered to the ground plane. Check for RoHS compliance documentation and ensure the ordering part number corresponds exactly to the Analog Devices manufacturing specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution and 210 MSPS sampling rate are required for wideband signal processing. Ensure the system design accommodates the 1.8 V supply voltage and LVDS output interface. Consider the pin compatibility with the AD9634 if migration from a 12-bit architecture is planned. Verify that the input frequency range up to 350 MHz aligns with the application's bandwidth needs.

Analog To Digital Converters (ADC) Part Context

The AD9642BCPZ-210 belongs to the AD9642 family of high-speed, low-power ADCs designed for communications applications. It shares pinout compatibility with the AD9634 and AD6672, facilitating design flexibility. The device is specified over the industrial temperature range of -40°C to +85°C and is housed in a compact 32-lead LFCSP package suitable for space-constrained boards.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9642BCPZ-170 and AD9642BCPZ-250 are direct functional substitutes within the same family, differing only in maximum sampling rates. For migration from lower resolution, the AD9634 series offers pin-compatible 12-bit alternatives.
