AD9250BCPZ-250

Overview

The AD9250BCPZ-250 is a dual-channel, 14-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It supports sampling rates up to 250 MSPS and features JESD204B serial digital outputs. The device operates on a single 1.8 V supply with total power consumption of 711 mW at maximum speed. Key performance metrics include a signal-to-noise ratio (SNR) of 70.6 dBFS and a spurious-free dynamic range (SFDR) of 88 dBc at an input frequency of 185 MHz. It utilizes a multistage differential pipelined architecture with integrated output error correction logic.

Feature Summary

• Configurable JESD204B output block supporting up to 5 Gbps per lane
• On-chip phase-locked loop (PLL) for clock multiplication
• Proprietary differential input maintaining excellent SNR up to 400 MHz
• Standard SPI interface for control and configuration

Applications

• TD-SCDMA, WiMAX, W-CDMA, CDMA2000, GSM, EDGE, LTE systems
• DOCSIS 3.0 CMTS upstream receive paths
• HFC digital reverse path receivers
• Radar receivers
• General-purpose software radios

Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's current ordering guide to confirm package type and lead-free status. Ensure the '-250' speed grade matches the required sampling rate specifications for the target application design.

Selection Notes

Select this component when high-speed data conversion with low pin count is required. The JESD204B interface simplifies PCB layout compared to parallel interfaces. Verify that the receiving FPGA or ASIC supports the JESD204B standard and can handle the required data rates.

Part Context

This part belongs to the AD9250 family of high-speed dual ADCs. It is designed for communications applications requiring low cost, small size, wide bandwidth, and versatility. The device integrates an internal voltage reference and duty cycle stabilizer to simplify system design.

Replacement Considerations

Check for AD9250BCPZ-170 for lower speed requirements. Verify compatibility with other JESD204B-compatible ADCs from Analog Devices if pin-out and electrical characteristics allow for direct substitution.
