AD9173BBCZ - Dual 16-Bit 12.6 GSPS RF DAC | Analog Devices
MPN: AD9173BBCZ ✓ نشطAD9173BBCZ نظرة عامة
A digital-to-analog converter (DAC) is a device that converts digital signals into analog voltages or currents. In RF systems, high-speed DACs like the AD9173 are essential for generating wideband waveforms directly at radio frequencies, eliminating the need for multiple upconversion stages. The AD9173 belongs to the family of RF transceivers and data converters, which are critical components in modern communication systems, radar, and test equipment.
Key features of the AD9173BBCZ include dual 16-bit DACs, a maximum sample rate of 12.6 GSPS, and a JESD204B interface with 8 lanes at 15.4 Gbps. The on-chip clock multiplier allows the use of a lower-frequency reference clock, simplifying system design. The device also offers a flexible digital upconversion (DUC) engine with multiple channelizers, supporting both single-band and multiband operation. These features enable direct RF synthesis, reducing system complexity and power consumption.
From a technical perspective, the AD9173 utilizes a high-speed CMOS DAC core with advanced interpolation filters and numerically controlled oscillators (NCOs). The JESD204B interface supports subclass 1 deterministic latency, ensuring precise synchronization in multi-chip systems. The device operates from a 1.0V core supply and 1.8V/3.3V I/O supplies, with power dissipation typically around 2.5W at full sample rate. The 144-ball BGA-ED package (10x10 mm) provides excellent thermal performance and signal integrity for high-frequency operation.
Typical applications for the AD9173BBCZ include wireless infrastructure (4G/5G base stations), radar systems, electronic warfare, and test and measurement equipment. Its high sample rate and wide bandwidth make it suitable for generating wideband signals in software-defined radios and direct RF sampling architectures. The device's multiband capability allows a single DAC to generate multiple carriers simultaneously, reducing component count and cost.
When designing with the AD9173, careful attention must be paid to power supply decoupling and clock jitter. Use low-noise LDOs for analog supplies and a high-quality clock source to achieve optimal SNR and SFDR. The JESD204B interface requires proper termination and impedance matching to ensure error-free data transfer at 15.4 Gbps.

ملاحظات التصميم
The AD9173BBCZ requires clean power supplies for optimal performance. Use low-noise LDO regulators for AVDD and DVDD, and place decoupling capacitors (100nF and 10uF) close to each power pin. Avoid sharing supplies between analog and digital domains to prevent noise coupling.
For the 144-ball BGA package, use a multilayer PCB with dedicated ground planes. Ensure proper impedance control for the JESD204B differential pairs (100 ohm differential) and clock lines. Keep high-speed traces short and use via stitching to minimize inductance.
The AD9173BBCZ dissipates up to 2.5W, so adequate thermal management is required. Use thermal vias under the exposed pad and connect to a large copper pour. In high ambient temperature environments, consider forced air cooling or a heatsink.
