AD9634BCPZRL7-170

Analog To Digital Converters (ADC) Overview

The AD9634BCPZRL7-170 is a single-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 170 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. Power consumption is 360 mW at the maximum sample rate, supported by 1.8 V analog and digital supply voltages. It includes an integer 1-to-8 clock divider, a duty cycle stabilizer, and energy-saving power-down modes.

Analog To Digital Converters (ADC) Feature Summary

• Multistage differential pipelined ADC core with integrated output error correction logic for high linearity.
• Flexible analog input range supporting user-selectable spans from 1.4 V p-p to 2.0 V p-p.
• Integrated ADC clock duty cycle stabilizer to maintain performance despite clock variations.
• Three-wire SPI-compatible serial port interface for register programming and readback.

Analog To Digital Converters (ADC) Applications

• Communications systems including TD-SCDMA, WiMAX, W-CDMA, CDMA2000, GSM, EDGE, and LTE.
• Diversity radio systems and multimode digital receivers.
• I/Q demodulation systems and smart antenna configurations.
• Ultrasound equipment and general-purpose software radios.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix matches the required conversion rate, as the -170 designation indicates a 170 MSPS limit. Confirm the RL7 suffix corresponds to the reel packaging format required for automated assembly processes. Ensure the component meets RoHS compliance standards applicable to your manufacturing region before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 12-bit resolution and 170 MSPS sampling rate are sufficient for the application bandwidth. Consider the AD9634-210 or AD9634-250 variants if higher throughput is necessary. Verify that the system clock frequency allows for the integer division ratios provided by the internal divider. Ensure the PCB layout supports the LFCSP-32 package thermal requirements for reliable operation across the industrial temperature range.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9634 family of high-speed, low-power ADCs designed for communications infrastructure. It shares pin compatibility with the AD9642 and AD6672, facilitating design migration between different resolution and speed grades within the Analog Devices portfolio. The device addresses market demands for compact, versatile solutions in multi-standard base station applications.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9634BCPZ-170 is a tray-packaged equivalent with identical electrical specifications. For higher performance requirements, the AD9634BCPZ-210 and AD9634BCPZ-250 offer increased sampling rates while maintaining the same pinout and functionality.
