AD9161BBCZ

Overview

The AD9161BBCZ is a high-performance, single-channel, 11-bit RF digital-to-analog converter (DAC) manufactured by Analog Devices. It supports data rates up to 6 GSPS and achieves an effective update rate of up to 12 GSPS using a quad-switch architecture with a 2× interpolator filter. The device features a maximum DAC update rate of 6.4 GSPS at VDDx1 = 1.3 V ± 2%. Key electrical parameters include an integral nonlinearity (INL) of ±2.7 LSB and differential nonlinearity (DNL) of ±1.7 LSB. It operates on analog supply voltages of 2.5 V (VDD25_DAC), 1.2 V (VDD12A/VDD12_CLK), and -1.2 V (VNEG_N1P2), alongside digital supplies of 1.2 V (DVDD) and 2.5 V (IOVDD). The component is housed in a 169-ball, 11 mm × 11 mm, 0.8 mm pitch CSP_BGA package.

Feature Summary

• Quad-switch DAC core with 2× interpolator filter enabling up to 12 GSPS effective update rate.
• Up to eight JESD204B SERDES lanes for flexible channel speed and configuration.
• Mix-Mode operation allows RF carrier reconstruction in second and third Nyquist zones up to 7.5 GHz.
• Programmable output current ranging from 8 mA to 38.76 mA.

Applications

• Broadband communications systems
• DOCSIS 3.1 cable modem termination system (CMTS)/video on demand (VOD)/edge quadrature amplitude modulation (EQAM)
• Wireless communications infrastructure (W-CDMA, LTE, LTE-A, point to point)
• Instrumentation and automatic test equipment (ATE)
• Radars and jammers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and ball material specifications. Ensure that power supply filtering networks are designed according to the datasheet recommendations for VDD12_CLK and VDD12A pins to achieve lowest noise performance. Confirm thermal management requirements, as clock speeds exceeding 5.1 GSPS require a maximum junction temperature of 105°C to prevent device damage.

Selection Notes

Select the AD9161BBCZ when an 11-bit resolution is required for high-speed RF applications. This package variant utilizes the 169-ball, 11 mm × 11 mm, 0.8 mm pitch CSP_BGA form factor. Consider the AD9162 if 16-bit resolution is necessary, or the smaller 165-ball, 8.0 mm × 8.0 mm package if board space is constrained. Verify that the application supports the JESD204B interface standard and can accommodate the required SERDES lane configurations.

Part Context

The AD9161BBCZ belongs to the AD9161/AD9162 family of high-speed RF DACs. These devices are designed for demanding signal synthesis applications requiring wide bandwidth and high dynamic range. The family shares a common functional architecture but differs in resolution (11-bit vs. 16-bit) and available package options. The BBCZ suffix specifically denotes the 169-ball CSP_BGA package configuration.

Replacement Considerations

Public confirmed substitute part numbers: AD9162BBCZ (16-bit version, same package).
