AD9162BBCAZ

Overview

The AD9162BBCAZ is a 16-bit single-channel RF digital-to-analog converter (DAC) from Analog Devices. It supports a minimum DAC update rate of 12 GSPS and direct RF synthesis at 6 GSPS. The device features a quad-switch architecture with a bypassable 2× interpolator filter, enabling operation in baseband (DC to 2.5 GHz), 2× NRZ (DC to 6 GHz), and Mix-Mode (1.5 GHz to 7.5 GHz). Key electrical parameters include an integral nonlinearity (INL) of ±2.7 LSB, differential nonlinearity (DNL) of ±1.7 LSB, and a programmable full-scale output current ranging from 8 mA to 38.76 mA. It utilizes up to eight JESD204B SERDES lanes for data input and an SPI interface for configuration.

Feature Summary

• 16-bit resolution with a maximum DAC update rate of 12 GSPS using the 2× NRZ mode.
• Mix-Mode operation allows RF carrier reconstruction in the second and third Nyquist zones up to 7.5 GHz.
• Supports DOCSIS 3.1 compliance with wide bandwidth capability and high dynamic range.
• Configurable interpolation factors including 2×, 3×, 4×, 6×, 8×, 12×, 16×, and 24×.

Applications

• Broadband communications systems
• DOCSIS 3.1 cable modem termination systems (CMTS), video on demand (VOD), and edge quadrature amplitude modulation (EQAM)
• Wireless communications infrastructure including W-CDMA, LTE, and LTE-A
• Radar and jammer systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and ball count. The AD9162BBCAZ designation corresponds to the 169-ball CSP_BGA package variant. Ensure compatibility with system power supply requirements, specifically the 2.5 V analog supply and 1.2 V digital supplies, before procurement.

Selection Notes

Select the AD9162BBCAZ when 16-bit resolution is required for high linearity applications. This model is distinct from the AD9161, which offers 11-bit resolution. Consider the 169-ball package dimensions (11 mm × 11 mm) for PCB layout constraints. Verify that the application requires the higher dynamic performance provided by the 16-bit architecture compared to lower-resolution alternatives.

Part Context

The AD9162 is part of the AD9161/AD9162 family of high-performance RF DACs designed for demanding high-speed applications. While sharing the same core architecture and update rates as the 11-bit AD9161, the AD9162 provides enhanced resolution. The BBCAZ suffix identifies the specific 169-ball, 11 mm × 11 mm, 0.8 mm pitch CSP_BGA package option available within this product line.

Replacement Considerations

The AD9161 serves as a functional alternative if 11-bit resolution is sufficient for the application. Both devices share identical pinouts for the respective packages and similar operational characteristics, differing primarily in resolution and associated dynamic performance metrics.
