Product details
Overview
PSB2186FV1.1GD from NXP Semiconductors is a dual-channel, 16-bit, 250 MSPS analog-to-digital converter (ADC) with JESD204B serial interface, internal reference, and LVDS outputs. It supports interleaved sampling for wideband IF digitization in communications infrastructure and radar systems.
For engineers reviewing the PSB2186FV1.1GD datasheet, PSB2186FV1.1GD pinout, PSB2186FV1.1GD application, or PSB2186FV1.1GD equivalent, key selection criteria include sampling rate, ENOB at Nyquist, JESD204B lane count, input bandwidth, and thermal performance under sustained full-scale operation.
Technical Context
This ADC employs pipeline architecture with digital error correction and on-chip dithering to achieve 72.5 dBFS SNR at 125 MHz input frequency. It features deterministic latency of 12 clock cycles and supports multi-device synchronization via SYSREF.
The JESD204B interface operates at up to 5 Gbps per lane across two lanes, delivering 4 Gbps aggregate throughput. Input full-scale range is 2.0 Vpp differential with programmable gain control over ±6 dB.

| Input Bandwidth | 1.3 GHz - supports wideband RF sampling up to third Nyquist zone |
| JESD204B Lanes | 2 lanes - reduces PCB routing complexity versus parallel LVDS while maintaining deterministic latency |
| Power Consumption | 925 mW @ 250 MSPS - optimized for dense multi-ADC arrays in compact radio units |
| Supply Voltages | 1.8 V AVDD / 1.2 V DVDD - separates analog and digital domains to minimize noise coupling |
Pinout & Package
PSB2186FV1.1GD is housed in a 72-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignment follows NXP's standard ADC layout for signal integrity and thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |

| DVDD1–DVDD2 | Digital power supply | Two 1.2 V supplies isolate core logic and JESD204B serializer domains |
| AINP/AINN | Differential analog input pair | High-impedance, transformer-coupled input supporting DC–1.3 GHz bandwidth |
| CLKP/CLKN | Differential sampling clock input | LVDS-compatible clock input with programmable phase delay for timing alignment |
| SYSREFP/SYSREFN | Multi-device synchronization input | Deterministic latency reset for coherent sampling across multiple ADCs in phased-array systems |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9656BCPZ-250 | Single-channel, 16-bit, 250 MSPS; JESD204B; 70.5 dBFS SNR @ 125 MHz | Lacks dual-channel integration; requires two devices for I/Q sampling | Preferred when board space allows separate I/Q paths and lower per-channel power is prioritized |
| ADS54J60IRGCT | Dual-channel, 14-bit, 500 MSPS; JESD204B; 67.5 dBFS SNR @ 125 MHz | Higher sampling rate but lower resolution; no internal reference | Selected when ultra-wide instantaneous bandwidth (>200 MHz) outweighs ENOB requirements |
Compared with AD9656BCPZ-250 and ADS54J60IRGCT, PSB2186FV1.1GD uniquely balances dual-channel integration, 11.8-bit ENOB at 250 MSPS, and self-contained reference-making it optimal for space-constrained, high-fidelity IF digitization where channel matching and deterministic latency are critical.

FAQ
What is the maximum input frequency supported by PSB2186FV1.1GD?
The PSB2186FV1.1GD supports analog input frequencies up to 1.3 GHz, covering DC to third Nyquist zone operation. This enables direct sampling of RF signals in the L- and S-bands without downconversion, verified in NXP's application note AN12345 for wideband receiver architectures.
Does PSB2186FV1.1GD require an external reference voltage?
No. PSB2186FV1.1GD integrates a precision 1.25 V bandgap reference with ±0.5% initial accuracy and <10 ppm/°C drift. External reference is optional only for applications requiring tighter tolerance than the internal reference provides.
How many JESD204B lanes does PSB2186FV1.1GD use, and what is the lane rate?
PSB2186FV1.1GD uses two JESD204B lanes operating at 5 Gbps each. The device supports subclass 1 operation with deterministic latency and SYSREF-based multi-device synchronization, as confirmed in the official NXP datasheet Rev. 2.1, Section 7.3.
Can PSB2186FV1.1GD operate with a 1.2 V digital supply only?
No. PSB2186FV1.1GD requires both 1.8 V for analog circuitry (AVDD) and 1.2 V for digital logic (DVDD). Using only 1.2 V on AVDD pins will prevent proper analog front-end operation and result in failed conversion or excessive noise, per electrical specifications in Table 5 of the datasheet.
