Product details
Overview
AD9253TCPZ-125EP from Analog Devices is a quad-channel, 14-bit, 125 MSPS serial LVDS analog-to-digital converter operating from a single 1.8 V supply, delivering 74 dB SNR and 90 dBc SFDR at Nyquist, with 650 MHz full-power analog bandwidth-designed for medical ultrasound beamforming and high-speed quadrature radio receivers.
For engineers reviewing the AD9253TCPZ-125EP datasheet, AD9253TCPZ-125EP pinout, AD9253TCPZ-125EP application, or AD9253TCPZ-125EP equivalent, key selection considerations include military-grade temperature operation (−55°C to +125°C), per-channel power-down capability (<2 mW disabled), programmable LVDS output alignment, built-in digital test pattern generation, and RoHS-compliant 48-lead LFCSP packaging.
Technical Context
The AD9253TCPZ-125EP integrates four independent pipeline ADC cores with on-chip sample-and-hold, clock management, and serial LVDS digital serializers. Each channel supports 2 V p-p differential analog input, 1.0 V internal reference, and programmable output resolution via SPI.
It features dual LVDS data lanes per channel (D0±x, D1±x), plus dedicated DCO± and FCO± outputs for DDR data capture and frame synchronization. Clock input accepts LVPECL/LVDS/CMOS levels, and multichip sync is enabled via SYNC pin with programmable clock divider.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - delivers 16,384 discrete amplitude levels for high-fidelity signal digitization in wide dynamic range systems. |
| Sampling Rate | 125 MSPS - supports real-time capture of IF signals up to 650 MHz analog bandwidth without undersampling constraints. |
| SNR / SFDR | 74 dB / 90 dBc (to Nyquist) - enables clean spectral separation in dense RF environments such as diversity radio receivers. |
| Power Consumption | 440 mW total (four channels, ANSI-644 LVDS mode) - achieves 110 mW/channel efficiency critical for compact, convection-cooled systems. |
| Operating Temperature | −55°C to +125°C - qualified for extended-life deployment in avionics, downhole tools, and space-qualified electronics. |
| Analog Input Range | 2 V p-p differential - simplifies front-end driver design by eliminating external gain stages in many ultrasound and test equipment applications. |
| Digital Interface | Serial LVDS (ANSI-644 compliant) - reduces PCB routing complexity and EMI vs parallel CMOS, with programmable bit orientation and DDR timing. |
Pinout & Package
The AD9253TCPZ-125EP is housed in a RoHS-compliant, 48-lead Lead Frame Chip Scale Package (LFCSP_WQ), 7 mm × 7 mm body, with exposed thermal pad requiring solder connection to analog ground for thermal and noise performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+A / VIN−A VIN+B / VIN−B VIN+C / VIN−C VIN+D / VIN−D |
Differential analog inputs for Channels A–D | Accepts 2 V p-p differential signals; common-mode voltage fixed at 0.9 V; supports DC-coupled or AC-coupled front ends. |
| CLK+ / CLK− | Differential sampling clock input | Accepts LVPECL/LVDS/CMOS logic; enables precise aperture jitter control (135 fs rms) for high-SFDR performance. |
| D0±A–D / D1±A–D | LVDS serialized data outputs (2 lanes × 4 channels) | Delivers 14-bit data in DDR format; supports ANSI-644 or low-power reduced-swing LVDS modes via SPI configuration. |
| DCO± / FCO± | Data and frame clock outputs | DCO± clocks DDR data capture; FCO± marks byte boundaries; both support multichip synchronization and skew compensation. |
| CSB / SCLK / SDIO/OLM | 3-wire SPI interface | Enables full register access for power modes, test patterns, clock dividers, output alignment, and resolution programming. |
| PDWN / SYNC / VCM / VREF / RBIAS | Control, reference, and bias terminals | PDWN enables per-device power-down; SYNC synchronizes clock dividers across multiple AD9253TCPZ-125EP devices; RBIAS sets internal bias current via 10 kΩ resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Quad 14-bit ADC in 7 mm × 7 mm LFCSP | Reduces board area by >60% vs discrete quad-ADC solutions while maintaining channel isolation >95 dB. |
| Programmable LVDS output modes | Switches between full-swing ANSI-644 (345 mV VOD) and low-power reduced-swing (200 mV VOD) without hardware change. |
| Built-in digital test pattern generation | Supports deterministic, pseudorandom, and custom SPI-loaded patterns-eliminates external pattern generators during production test. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9257BCPZ-125 | Commercial-grade (−40°C to +85°C); same 14-bit/125 MSPS spec but no EP qualification or military temp support. | Lacks radiation-hardened process and extended temp validation-unsuitable for aerospace or downhole use. | Select AD9257BCPZ-125 only for cost-sensitive commercial test gear where extended temperature is not required. |
| ADS52J90IRGCT | Texas Instruments quad 14-bit 125 MSPS ADC with JESD204B interface instead of LVDS; higher power (540 mW), no built-in test patterns. | Requires FPGA with JESD204B PHY; adds serialization overhead and layout complexity vs self-timed LVDS outputs. | Choose ADS52J90IRGCT only when system already uses JESD204B infrastructure and needs deterministic lane alignment across multiple devices. |
Compared with AD9257BCPZ-125, the AD9253TCPZ-125EP provides guaranteed operation at −55°C and +125°C with controlled manufacturing baseline, while versus ADS52J90IRGCT it eliminates JESD204B PHY dependency and reduces FPGA resource usage via embedded LVDS serialization and multichip sync.

FAQ
What is the absolute maximum junction temperature for the AD9253TCPZ-125EP?
The AD9253TCPZ-125EP has an absolute maximum junction temperature of 150°C, as specified in Table 5 of its preliminary technical data sheet. This rating ensures safe operation under worst-case ambient and power dissipation conditions within the −55°C to +125°C ambient range. Thermal design must maintain junction temperature below this limit using the provided θJA (20.3°C/W) and θJC (6.1°C/W top) values for the 48-lead LFCSP package.
Does the AD9253TCPZ-125EP support external voltage reference operation?
Yes, the AD9253TCPZ-125EP supports both internal and external reference configurations. Pin 42 (VREF) serves as both output (1.0 V internal reference) and input; applying an external 1.0 V reference disables the internal reference. The SENSE pin (Pin 41) selects reference mode, and the input common-mode voltage (VCM = 0.9 V) remains fixed regardless of reference source-ensuring consistent analog input scaling for the AD9253TCPZ-125EP.
How many clock cycles of pipeline latency does the AD9253TCPZ-125EP exhibit?
The AD9253TCPZ-125EP exhibits a fixed pipeline latency of 16 clock cycles, as confirmed in Table 4 (Switching Specifications). This deterministic latency applies uniformly across all four channels and is independent of SPI configuration, output mode, or power state-enabling precise time-of-flight calculations in ultrasound and radar systems using the AD9253TCPZ-125EP.
Can the AD9253TCPZ-125EP operate with a 1.0 V supply on AVDD or DRVDD?
No, the AD9253TCPZ-125EP requires AVDD and DRVDD supplies within 1.7 V to 1.9 V, with nominal 1.8 V operation. Table 1 (DC Specifications) explicitly defines AVDD and DRVDD min/max ratings, and operation outside this range risks parametric failure or damage. The AD9253TCPZ-125EP is not rated for 1.0 V supply-its internal biasing, reference, and LVDS drivers depend on the 1.8 V rail.
Is the exposed thermal pad on the AD9253TCPZ-125EP electrically connected to AGND?
Yes, the exposed thermal pad on the AD9253TCPZ-125EP is internally connected to AGND (analog ground), as stated in Table 7 (Pin Function Descriptions) and Figure 2 notes. It must be soldered to a solid analog ground plane on the PCB to ensure proper thermal dissipation, low-noise performance, and functional stability-failure to connect the pad may result in degraded SNR, increased jitter, or device malfunction.
