5962-0423001QXC Présentation
What is an ADC? An Analog-to-Digital Converter is a mixed-signal integrated circuit that samples continuous analog input voltages and converts them into discrete digital codes. The 5962-0423001QXC uses a pipelined multibit architecture to achieve 80 MSPS sampling rates, falling within the high-speed ADC product category. Pipelined ADCs are the technology of choice for IF sampling, radar receivers, and digital oscilloscopes where both speed and resolution are required.
Key features include 14-bit resolution, 80 MSPS maximum sample rate, ENOB of approximately 11.5 bits at Nyquist input, and SFDR exceeding 80 dBc. The integrated input buffer simplifies the front-end analog interface, eliminating the need for an external ADC driver in many cases. The device operates from a single 3.3V analog supply and 3.3V digital supply with separate grounds for noise isolation.
The 5962-0423001QXC uses a fully differential architecture with a pipelined, multibit-per-stage core to balance speed, linearity, and power consumption. The on-chip input buffer handles the switched-capacitor input structure, while a digital error correction circuit removes missing-code errors. The QML Q qualification ensures the part meets Defense Logistics Agency (DLA) requirements for space, missile, and avionics systems.
Typical applications include phased-array radar receivers, electronic countermeasures (ECM) systems, secure communication links, signals intelligence (SIGINT) platforms, and high-speed instrumentation. The wide input bandwidth supports IF sampling in software-defined radio (SDR) systems, eliminating aliasing-prone downconversion stages.
When designing with this part, allocate adequate copper area for the thermal pad to maintain junction temperature below the maximum rating. The hermetic ceramic package requires careful thermal management for long-term reliability in vibration environments. Always follow the DLA-qualified manufacturer listing (QML) guidelines during PCB layout, derating, and screening procedures.

Notes de conception
Estimated: The 52-TQFP-EP (10x10) hermetic ceramic package has a typical theta_JA of approximately 25 C/W in still air, and the package datasheet recommends connecting the thermal pad to the analog ground plane with at least 4 thermal vias. For QML Q designs exposed to 85C case temperature, verify that the PCB copper area around the EP keeps junction temperature below the maximum rating; use the device family thermal application note from Analog Devices for derating calculations.
Separate the analog and digital ground planes under the device and connect them only at a single ground point near the analog supply decoupling capacitors. Each AVDD/DRVDD pin needs a 0.1 uF ceramic decoupling capacitor placed within 50 mils of the pin. Clock input traces (ENCODE+/ENCODE-) should be routed as a matched differential pair with characteristic impedance of 100 ohms differential to maintain clock duty cycle at 80 MSPS.
Use a single solid ground plane on the inner PCB layer and keep the analog input traces (AIN+/AIN-) routed as a 100 ohm differential microstrip with no stub branches. The reference decoupling node (CAPT/CAPB/SENSE) must be bypassed with low-ESR ceramic capacitors per the datasheet to maintain full-bandwidth SFDR at high input frequencies up to 150 MHz.
QML Q parts require careful supply decoupling: inadequate bypass results in degraded SFDR and harmonics that fail production test criteria. Use the OE (output enable, active low) pin to place outputs in a high-Z state during the start-up, and ensure no power supply inrush exceeds the datasheet current limit. When troubleshooting, do not rely on commercial plastic-packaged samples for military screening development - the only valid design vehicle is the QML Q sample with documentation.
The 14-bit parallel output bus (DB13..DB0) must be series-terminated near the driver at the source impedance matching the trace characteristic impedance (50 ohms per line / 100 ohm LVDS-equivalent for parallel CMOS/LVTTL outputs). At 80 MSPS, clock-to-data timing budget is approximately 6.25 ns - exceeding this timing without matched impedance creates metastability. Use IBIS model simulation of the AD6645 family before fabrication.
