Replacement verdict
Not a drop-in replacement
The AFE58JD28ZAV and AFE5803ZCF are not drop-in replacements for one another. The AFE58JD28ZAV is an 8-channel ultrasound analog front end with integrated JESD204B serial output, digital demodulation, and CW Doppler processing, while the AFE5803ZCF is a 16-channel device with LVDS parallel output and a different package and channel architecture. Designers must validate channel count, digital interface, package footprint, and signal-chain configuration before considering any substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AFE58JD28ZAV | AFE5803ZCF | Why it matters |
|---|---|---|---|
| Number of Channels | 16 | 8 | Channel count determines how many transducer elements can be processed simultaneously; a direct functional substitutability constraint. |
| ADC Resolution | 14 bit | 12 bit | Higher resolution improves dynamic range and image quality in ultrasound receive chains. |
| Maximum Sampling Rate | 65 MSPS | 65 MSPS | Sampling rate sets the maximum signal bandwidth the AFE can digitize for a given application. |
| LNA Gain Range | 0 to 24 dB | 0 to 24 dB | Low-noise amplifier gain range affects sensitivity and the ability to match different transducer signal levels. |
| Package | NFBGA (ZAV) | NFBGA (ZCF) | Package footprint and pinout must match for board-level drop-in compatibility. |
| Supply Voltage | 1.8 V / 3.3 V | 1.8 V / 3.3 V | Supply rails must be compatible with the existing power architecture of the system. |
| Interface | LVDS | LVDS | Output interface compatibility determines whether the downstream FPGA or receiver can accept the data stream. |
| Operating Temperature Range | -40 to 85 °C | -40 to 85 °C | Temperature range must cover the target application environment for reliable operation. |

Frequently asked questions
What are the AFE58JD28ZAV and AFE5803ZCF?
The AFE58JD28ZAV is a 16-channel, 14-bit, 65-MSPS analog front-end (AFE) with JESD204B serial output from Texas Instruments, intended for ultrasound and medical imaging systems. The AFE5803ZCF is an 8-channel, 14-bit, 65-MSPS AFE with LVDS serial output, also from Texas Instruments, targeting similar ultrasound signal-chain applications.
How do the channel counts of the AFE58JD28ZAV and AFE5803ZCF differ?
The AFE58JD28ZAV integrates 16 receive channels, while the AFE5803ZCF integrates 8 receive channels. This difference directly affects channel density per device and the number of devices required in a multi-channel ultrasound system.
What output interface does each device use?
The AFE58JD28ZAV provides a JESD204B serial output interface, whereas the AFE5803ZCF provides an LVDS serial output interface. The JESD204B interface reduces the number of high-speed serial lanes required compared with LVDS, which can simplify board routing in high-channel-count designs.
Are the AFE58JD28ZAV and AFE5803ZCF pin-to-pin or package compatible?
No. The AFE58JD28ZAV is supplied in a ZAV package, and the AFE5803ZCF is supplied in a ZCF package. The two devices differ in channel count, output interface, and package, so they are not direct drop-in replacements and require separate PCB footprints and layout validation.
Do both devices share the same 14-bit, 65-MSPS conversion specification?
Yes. Both the AFE58JD28ZAV and AFE5803ZCF are specified as 14-bit analog front-ends with a maximum sampling rate of 65 MSPS, so their per-channel conversion resolution and sample-rate capability are comparable, while channel count and digital output interface differ.
Which device is better suited to high-channel-density ultrasound designs?
The AFE58JD28ZAV is generally better suited to high-channel-density designs because it integrates 16 channels per device and uses JESD204B serial output, which reduces the number of serial lanes and interconnect complexity compared with the 8-channel, LVDS-output AFE5803ZCF. Final selection should be validated against the system's channel budget, FPGA serial interface capability, and power/thermal constraints.
Can the AFE5803ZCF be used as a substitute for the AFE58JD28ZAV in an existing design?
No, not as a direct substitute. The AFE5803ZCF has half the channel count (8 versus 16), uses an LVDS output interface instead of JESD204B, and is housed in a different package (ZCF versus ZAV). Any substitution would require redesign of the analog front-end channel count, digital interface, and PCB layout, and must be validated against the manufacturer datasheets.
