Replacement verdict
Compatible functional replacement candidate
The AD9176BBPZ and AD9172BBPZ are functionally comparable dual-channel 16-bit high-speed DACs sharing the same package and pinout, making the AD9176BBPZ a viable replacement candidate for the AD9172BBPZ in most designs. The primary distinction lies in maximum output update rate, so designers should confirm that the higher sample-rate capability and any associated clocking or power considerations align with the target application before substituting.

Frequently asked questions
What are the key differences between the AD9176BBPZ and AD9172BBPZ?
The AD9176BBPZ is a dual-channel, 16-bit, 12 GSPS RF DAC with a maximum input data rate of 12 GSPS per channel and an on-chip PLL. The AD9172BBPZ is a dual-channel, 16-bit, 12 GSPS RF DAC with a maximum input data rate of 6 GSPS per channel. Both are pin-compatible in the same 144-ball BGA package and share the same JESD204B interface, but the AD9176 supports higher input data rates and includes additional digital signal processing features such as a programmable FIR filter and a numerically controlled oscillator (NCO) per channel.
Are the AD9176BBPZ and AD9172BBPZ pin-compatible?
Yes. Both devices are offered in the same 144-ball BGA package (12 mm × 12 mm) with identical pin assignments, allowing a common PCB footprint. However, designers must verify that the higher input data rate and additional DSP features of the AD9176BBPZ are supported by the surrounding circuitry before substituting one for the other.
What is the maximum input data rate per channel for each device?
The AD9176BBPZ supports a maximum input data rate of 12 GSPS per channel, while the AD9172BBPZ supports a maximum input data rate of 6 GSPS per channel. Both devices provide a 16-bit DAC resolution and a maximum DAC update rate of 12 GSPS.
Do both devices include an on-chip PLL for clock generation?
Yes. Both the AD9176BBPZ and AD9172BBPZ integrate an on-chip phase-locked loop (PLL) with a programmable divider, allowing generation of the DAC sampling clock from a lower-frequency reference. This reduces the need for an external high-frequency clock source in the system design.
What digital signal processing features differ between the two devices?
The AD9176BBPZ includes a programmable FIR filter and a numerically controlled oscillator (NCO) per channel, enabling digital up-conversion and interpolation flexibility. The AD9172BBPZ provides interpolation filters and an NCO but does not include the programmable FIR filter block. Designers should consult the respective datasheets for the exact interpolation and channelizer configurations supported by each device.
Can the AD9172BBPZ be used as a drop-in replacement for the AD9176BBPZ?
Not directly. Although the devices are pin-compatible, the AD9176BBPZ supports a higher maximum input data rate (12 GSPS vs. 6 GSPS) and includes a programmable FIR filter that the AD9172BBPZ does not. A drop-in replacement is only possible if the system does not require the higher input data rate or the additional FIR filtering, and if all JESD204B link parameters and clocking requirements are revalidated against the AD9172BBPZ datasheet.
What JESD204B interface configurations do these DACs support?
Both the AD9176BBPZ and AD9172BBPZ support JESD204B subclass 1 deterministic latency with multiple lane configurations. The AD9176BBPZ supports higher lane rates to accommodate its 12 GSPS maximum input data rate, while the AD9172BBPZ supports lane rates sufficient for its 6 GSPS maximum input data rate. Exact lane count, lane rate, and converter configuration options should be verified in the respective manufacturer datasheets.
What are the typical applications for the AD9176BBPZ and AD9172BBPZ?
Both devices are wideband RF DACs intended for applications such as wireless base station transmitters, microwave point-to-point radios, satellite communications, and broadband cable infrastructure. The AD9176BBPZ is suited to applications requiring higher input data rates and additional digital filtering, while the AD9172BBPZ addresses applications where a 6 GSPS maximum input data rate is sufficient.
