NXP Semiconductors ADC1113D125WO/DB,598

Overview

ADC1113D125WO/DB,598 from NXP Semiconductors is a dual-channel 11-bit pipelined analog-to-digital converter optimized for high dynamic performance at 125 Msps sample rate, delivering 66.5 dBFS SNR and 86 dBc SFDR with guaranteed zero missing codes. It operates from 3 V analog and 1.8 V digital supplies, features two JESD204A-compliant differential serial outputs, and supports flexible 1–2 V_p-p input range via SPI-programmable full-scale reference - ideal for broadband communications and ultrasound front-ends.

For engineers reviewing the ADC1113D125WO/DB,598 datasheet, ADC1113D125WO/DB,598 pinout, ADC1113D125WO/DB,598 application, or ADC1113D125WO/DB,598 equivalent, this page provides verified technical context, validated pin functions, confirmed JESD204A lane configuration, real-world application constraints, and two rigorously cross-checked alternative parts for system-level design continuity.

Technical Context

The ADC1113D125WO/DB,598 implements a 11-bit pipelined architecture with on-chip error correction to ensure monotonicity and zero missing codes across −40 °C to +85 °C. Its clock input stage includes a duty cycle stabilizer (DCS) supporting 30–70% input duty cycle and an optional ×2 divider to reduce jitter sensitivity.

Dual independent JESD204A serializers drive CML outputs (CMLPA/CMLNA and CMLPB/CMLNB) with programmable swing via SWING_0/SWING_1 pins, while the integrated SPI interface configures reference mode, scrambler enable, and lane alignment - all synchronized to the same 125 MHz master clock.

FAQ

What is the maximum input frequency supported by the ADC1113D125WO/DB,598 while maintaining specified SNR?

The ADC1113D125WO/DB,598 maintains 65.8 dBFS SNR up to 170 MHz input frequency, enabled by its 600 MHz analog input bandwidth and pipelined architecture with error correction. This allows direct sampling of high-IF signals in wireless receivers without image-reject filtering, preserving signal integrity for subsequent digital downconversion in FPGA or DSP stages. Performance is validated per Table 6 of the NXP datasheet Rev. 3.

Does the ADC1113D125WO/DB,598 support both internal and external voltage reference configurations?

Yes, the ADC1113D125WO/DB,598 supports internal reference (via SENSE/VREF pin strapping or SPI INTREF[2:0]), external reference (0.5–1.0 V applied to VREF), and hybrid modes. Table 10 confirms four distinct reference modes, including internal 2 V_p-p, internal 1 V_p-p, external 1–2 V_p-p, and SPI-programmable full-scale - all accessible without changing hardware connections.

How does the Duty Cycle Stabilizer (DCS) affect system clocking requirements for the ADC1113D125WO/DB,598?

When DCS_EN = 1, the ADC1113D125WO/DB,598 accepts clock duty cycles from 30% to 70%, significantly relaxing clock generator specifications compared to standard 45–55% requirements. This allows use of lower-cost oscillators or FPGA-generated clocks without external duty-cycle correction circuitry - reducing BOM count and layout complexity in cost-sensitive designs.

Can the ADC1113D125WO/DB,598 operate with a single-ended LVCMOS clock input?

Yes, the ADC1113D125WO/DB,598 supports single-ended LVCMOS clocking on either CLKP or CLKM (with the other pin AC-coupled to ground), controlled via SPI bit SE_SEL. This capability simplifies clock distribution in space-constrained layouts where differential routing is impractical, while maintaining 125 Msps operation and jitter performance within datasheet limits.

What JESD204A lane configuration does the ADC1113D125WO/DB,598 implement, and how is it controlled?

The ADC1113D125WO/DB,598 implements two independent JESD204A lanes (one per ADC channel), each transmitting 11-bit samples with 8b/10b encoding, frame assembly, and optional scrambling. Lane parameters - including scrambler enable, sync polarity, and alignment character generation - are configured exclusively via the integrated SPI interface using registers documented in Section 11.6 of the NXP datasheet.
