Analog Devices Inc. AD9680BCPZRL7-500

Overview

AD9680BCPZRL7-500 from Analog Devices is a dual-channel, 14-bit, 500 MSPS analog-to-digital converter with JESD204B Subclass 1 serial output, integrated digital downconverters (DDCs), and programmable input termination. It delivers 68.6 dBFS SNR at 340 MHz input and −153 dBFS/Hz noise density, targeting IF sampling in wideband communications receivers.

For engineers reviewing the AD9680BCPZRL7-500 datasheet, AD9680BCPZRL7-500 pinout, AD9680BCPZRL7-500 application, or AD9680BCPZRL7-500 equivalent, key selection criteria include its 2 GHz analog input bandwidth, 1.46–2.06 V_p-p flexible input range, deterministic latency support via SYSREF±, and dual DDCs with 12-bit NCOs for multiband signal processing.

Technical Context

The AD9680BCPZRL7-500 implements two independent pipelined ADC cores with on-chip sample-and-hold and buffered differential inputs. Each channel feeds a dedicated DDC chain comprising a 12-bit numerically controlled oscillator (NCO) and up to four half-band decimation filters-configurable to bypass or enable frequency translation and decimation.

JESD204B Subclass 1 serialization supports 1-, 2-, or 4-lane output configurations with deterministic latency alignment across multiple devices using SYSREF± and SYNCINB±. Clock input accepts differential signals with integer divide-by-1/2/4/8, and internal reference eliminates external voltage reference requirements.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog input frequency supported by the AD9680BCPZRL7-500?

The AD9680BCPZRL7-500 supports a usable analog input full-power bandwidth of 2 GHz, enabling direct undersampling of IF signals up to S-band frequencies. This specification is verified per the Rev. E datasheet, Figure 14 and Table 1, and applies across the full industrial temperature range (−40°C to +85°C) with proper layout and power supply decoupling. The 2 GHz bandwidth is maintained regardless of the selected sampling rate (500 MSPS in this variant).

Does the AD9680BCPZRL7-500 require an external voltage reference?

No, the AD9680BCPZRL7-500 includes an internal 1.0 V ±0.5% voltage reference, eliminating the need for external reference components. This is confirmed in the Rev. E datasheet Section "Internal Voltage Reference" (Page 6) and DC Specifications Table 1. The internal reference is factory-trimmed and thermally compensated, supporting consistent ADC performance across temperature without added board area or cost.

How many JESD204B lanes does the AD9680BCPZRL7-500 support, and what is the maximum lane rate?

The AD9680BCPZRL7-500 supports configurable 1-, 2-, or 4-lane JESD204B Subclass 1 output. At 500 MSPS with default settings (M=2, N'=14, F=1), the maximum lane rate is 8.75 Gbps - well within the 12.5 Gbps limit for standard JESD204B physical layer implementation. Lane count and rate are programmable via SPI registers per Section "Configuring the JESD204B Link" (Page 73) of the Rev. E datasheet.

Can the AD9680BCPZRL7-500 perform frequency translation without external processing?

Yes, the AD9680BCPZRL7-500 integrates two independent digital downconverters (DDCs), each containing a 12-bit numerically controlled oscillator (NCO) and up to four half-band decimation filters. These DDCs operate entirely within the ADC die and can perform real-time frequency translation, channel selection, and sample-rate reduction - confirmed in the Rev. E datasheet Sections "Digital Downconverter (DDC)" (Page 49) and "Frequency Translation" (Page 55).

What is the power consumption of the AD9680BCPZRL7-500 under typical operating conditions?

The AD9680BCPZRL7-500 consumes 2.2 W total power (typical) at 500 MSPS with all features enabled and default SPI settings, as specified in Table 2 of the Rev. E datasheet (Page 7). Power breakdown includes 467 mA on AVDD1 (1.25 V), 490 mA on AVDD2 (2.5 V), and 101 mA on AVDD3 (3.3 V). Standby mode reduces consumption to 1.2 W, and full power-down lowers it to 700 mW.
