Texas Instruments ADC11DV200CISQX/NOPB

Overview

ADC11DV200CISQX/NOPB from Texas Instruments is a dual-channel, 11-bit, 200 MSPS analog-to-digital converter with pipelined architecture, internal sample-and-hold, and selectable LVDS or CMOS digital outputs. It operates from a single 1.8 V supply, delivers 10.06 ENOB at 70 MHz input, and supports IF sampling up to 900 MHz full-power bandwidth - deployed in wireless infrastructure baseband receivers and digital predistortion feedback paths.

For engineers reviewing the ADC11DV200CISQX/NOPB datasheet, ADC11DV200CISQX/NOPB pinout, ADC11DV200CISQX/NOPB application, or ADC11DV200CISQX/NOPB equivalent, key selection criteria include dual-channel interleaving latency (5 clock cycles), LVDS/CMOS output mode switching via OUTSEL, clock duty cycle stabilization (DCS), and 60-pin WQFN thermal performance with exposed pad grounding.

Technical Context

The ADC11DV200CISQX/NOPB implements a differential pipelined ADC architecture with digital error correction and on-chip sample-and-hold, enabling simultaneous conversion of two independent analog inputs (VIN A±, VIN B±) at up to 200 MSPS. Its unique S/H stage achieves 900 MHz full-power bandwidth while maintaining <0.3 ps rms aperture jitter.

It supports flexible reference configuration (internal 0.75 V or external 0.5–1.0 V), programmable data format (offset binary or 2's complement), and power scaling via REXT bias control. Output timing is synchronized to DRDY (LVDS DDR) or DRDYA/DRDYB (CMOS SDR), with conversion latency fixed at 5 clock cycles in both modes.

Key Specifications

Pinout & Package

FAQ

What is the minimum clock frequency supported by ADC11DV200CISQX/NOPB in LVDS mode with duty cycle stabilization enabled?

The ADC11DV200CISQX/NOPB supports a minimum clock frequency of 65 MHz in LVDS mode when the duty cycle stabilizer (DCS) is enabled. This is specified in the Timing and AC Characteristics table under "Minimum Clock Frequency" with DCS On condition. Operation below this frequency may result in degraded timing margins or failure to meet setup/hold requirements for DRDY and data outputs.

Can ADC11DV200CISQX/NOPB operate with an external reference voltage, and what is the valid input range?

Yes, ADC11DV200CISQX/NOPB supports external reference voltage applied to the VREF pin. The valid range is 0.2 V to 1.4 V: voltages between 0.2 V and 1.4 V select the external reference, while ≥1.4 V enables the internal 0.75 V reference. External reference must be bypassed with a 0.1 µF capacitor to AGND near the pin, as specified in the Pin Descriptions section.

How does the OUTSEL pin configure the digital output interface of ADC11DV200CISQX/NOPB?

The OUTSEL pin on ADC11DV200CISQX/NOPB selects the output interface standard: tying OUTSEL to AGND configures CMOS SDR outputs (DA0–DA10, DB0–DB10, DRDYA, DRDYB), while connecting it to VD enables LVDS DDR outputs (D0±–D10±, DRDY±). This hardware-selectable mode eliminates need for firmware reconfiguration or PCB redesign when interfacing to different host devices.

What is the conversion latency of ADC11DV200CISQX/NOPB, and how does it differ between LVDS and CMOS modes?

The ADC11DV200CISQX/NOPB has a fixed conversion latency of 5 clock cycles in LVDS mode and 5.5 clock cycles in CMOS mode, as defined in the Timing and AC Characteristics table. This latency represents the number of clock cycles between sampling and data availability at the output drivers - critical for deterministic timing in closed-loop DPD or beamforming systems.

Is the exposed thermal pad on ADC11DV200CISQX/NOPB required to be connected to ground, and why?

Yes, the exposed pad (EP) on ADC11DV200CISQX/NOPB must be soldered to AGND to ensure rated thermal performance and electrical stability. The datasheet explicitly states "Exposed pad must be soldered to ground plane to ensure rated performance," and thermal resistance θ_JA = 30°C/W assumes this connection. Omitting it risks junction temperature exceeding 150°C under full 450 mW LVDS load.
