Texas Instruments V62/06668-01XE

Overview

V62/06668-01XE from Texas Instruments is a radiation-hardened, military-grade 13-bit 250-MSPS analog-to-digital converter (ADC) designed for high-speed digitization of IF signals in harsh environments. It features fully buffered differential analog inputs, LVDS-compatible 13-bit parallel outputs, 2.2-VPP input range, and operates across –55°C to 125°C with 5-V analog and 3.3-V digital supplies. It is deployed in multichannel base station receivers and software-defined radio front ends requiring precision timing and extended temperature reliability.

For engineers reviewing the V62/06668-01XE datasheet, V62/06668-01XE pinout, V62/06668-01XE application, or V62/06668-01XE equivalent, this page delivers verified technical context, military-qualified thermal and dynamic performance data, package-specific layout guidance, and validated alternative options for space, defense, and avionics signal acquisition systems.

Technical Context

The V62/06668-01XE implements a monolithic pipeline architecture with bipolar BiCom3X process technology, using both clock edges to advance samples every half-cycle and achieving fixed 4-cycle latency. Its internal track-and-hold isolates the analog source from switching noise, while an integrated 2.4-V reference eliminates external biasing components.

Dynamic performance is optimized for wideband IF sampling: SNR reaches 69 dBc at 100 MHz input and 250 MSPS, SFDR is 77 dBc at 230 MHz, and analog input bandwidth extends to 800 MHz. Input common-mode is fixed at 2.4 V via internal 500-Ω resistors, yielding 1-kΩ differential input impedance and 1.5-pF input capacitance.

Key Specifications

Pinout & Package

FAQ

What is the absolute maximum clock input voltage for V62/06668-01XE?

The absolute maximum differential clock input voltage for V62/06668-01XE is ±2.5 V across CLK and CLK pins. Exceeding this rating risks permanent damage. Recommended operation uses a 3-VPP differential sine wave or square wave within the –0.3 V to AVDD + 0.3 V common-mode range. This specification is defined in the Absolute Maximum Ratings table of the official V62/06668-01XE datasheet.

Does V62/06668-01XE require an external reference voltage?

No, V62/06668-01XE does not require an external reference voltage. It integrates an internal 2.4-V reference generator that sets the input common-mode voltage and biases the analog core. The VREF pin provides access to this internal node but is not intended for external loading or regulation. This eliminates external reference components and associated layout complexity in V62/06668-01XE designs.

What is the latency of V62/06668-01XE and how is it timed?

V62/06668-01XE has a fixed latency of 4 clock cycles from rising edge of CLK to valid data on D[0:12]. This is confirmed in the Timing Characteristics table, where "Latency" is specified as 4 cycles. Data becomes valid on the DRY falling edge, which occurs 1.1 ns after the same rising clock edge. This deterministic delay enables precise synchronization in FPGA-based signal processing pipelines using V62/06668-01XE.

Can V62/06668-01XE be used with single-ended clock inputs?

Yes, V62/06668-01XE supports single-ended clock inputs. Per the Application Information section, CLK can be AC-coupled from a clock source while CLK is grounded via a 0.01-µF capacitor. Performance remains comparable to differential drive in low-jitter applications, though differential clocking is preferred for RF systems where common-mode noise rejection is critical. This capability is explicitly validated for V62/06668-01XE in TI's SGLS360 datasheet.

What thermal management is required for V62/06668-01XE at full load?

V62/06668-01XE dissipates ~2 W and requires active thermal management. The datasheet specifies θJA = 21.7°C/W with soldered thermal slug and no airflow. Designers must implement ≥36 thermal vias (6×6 array) connecting the PowerPAD to an internal ground plane, plus optional 250-LFPM airflow to achieve θJA = 15.4°C/W. Junction temperature must remain below 150°C across –55°C to 125°C ambient, making thermal vias non-optional in V62/06668-01XE layouts.
