5962R0423002VXC - 14-Bit 80MSPS Military ADC | Analog Devices
MPN: 5962R0423002VXC ✓ Hoạt động5962R0423002VXC Tóm tắt
An ADC (analog-to-digital converter) is a data-acquisition mixed-signal integrated circuit that samples a continuous analog input voltage and quantizes it into a discrete binary code; high-speed, high-resolution ADCs sit at the front end of receiver signal chains in radar, electronic warfare, software-defined radio, and digital instrumentation. ADCs of this family (Architecture: bipolar/CMOS pipeline) bridge the analog and digital subsystems and are part of the broader mixed-signal IC taxonomy that includes DACs, sample-and-hold amplifiers, and frequency converters.
Key datasheet features of the AD6645 die behind this SMD include 14-bit resolution (no missing codes), an input bandwidth exceeding 200 MHz, a 75 dB SNR to 10 MHz analog input, and a 7.3 ENOB effective number of bits at Nyquist. The 5962R version adds 100 krad(Si) radiation tolerance and full MIL-PRF-38535 Class V processing, traceability, and screening, which are mandatory for flight hardware in defense and aerospace programs.
The encoder uses a multi-stage pipelined architecture with an internal sample-and-hold and on-chip reference, providing low aperture jitter and excellent dynamic range for wideband IF sampling. Multiple ADCs of this family can be synchronized through an external encode clock, enabling coherent multi-channel receiver arrays.
Typical applications include military radar IF receivers, electronic-counter-measures (ECM) digital receivers, satellite-communication (SATCOM) modems, SIGINT and ELINT front-ends, and high-end digital oscilloscope front-ends. The hermetic ceramic GQFF package supports both leaded through-hole and surface-mount-style reflow profiles qualified to MIL-STD-1835 and JEDEC standards.
When designing with this SMD, follow MIL-PRF-38535 derating guidance (operate the part at 80% of maximum rated supply and clock to preserve reliability margin) and verify radiation-tolerance lot data against program requirements. Always check the Standardized Microcircuit Drawing (SMD) revision letter on each shipment against your qualified parts list.

Military Radar IF Receiver
The 5962R0423002VXC suits military radar IF-sampling receivers where the radar's intermediate-frequency signal (typically 10-70 MHz) must be digitized at the highest SNR possible to preserve MTI/clutter cancellation. With its 75 dB SNR to 10 MHz input, 14-bit resolution, and 80 MSPS throughput, the ADC delivers enough dynamic range to detect small targets while suppressing large clutter returns. The MIL-PRF-38535 Class V and 100 krad(Si) radiation tolerance allow direct deployment in airborne and shipboard radar front-ends. Reference: AD6645 datasheet and SMD 5962R04230.

Ghi chú thiết kế
Estimated: with analog 5 V/100 mA and digital 3.3 V/30 mA loads, total dissipation is approximately 0.6 W. Use low-ESR ceramic bypass caps on each AVDD/AVDD pair (10 µF + 100 nF) plus one 10 µF + 100 nF stack on each DVDD/DGND pair within 5 mm of the pads to avoid dynamic AVDD-droop-induced INL errors. Decouple encoder and analog grounds with a star connection at the package thermal pad to prevent digital return currents from coupling into the analog return path.
Although dissipation is modest (~0.6 W in the standard 80 MSPS configuration), the 52-terminal ceramic GQFF package is hermetic and thermal coupling is dominated by lead-frame geometry. For flight hardware under vacuum / no-air convection conditions, derate clock-rate and ambient temperature to keep junction rise below 25 K, and bond the thermal pad to a copper land through at least 6 thermal vias filled with copper to the inner GND plane.
Datasheet best practice: route analog input traces as microstrip or stripline, keep the encode-clock trace 100-ohm matched and isolated from analog input by a GND barrier, and place the input termination resistor within 5 mm of the AIN pin. Use split analog/digital power planes joined at a star point adjacent to the ADC; in multilayer boards dedicate one inner plane as a continuous analog ground under the ADC footprint to keep digital switching return currents out of the analog section. Reference: AD6645 datasheet application information.
Estimated: never assume the SMD 5962R0423002VXC is interchangeable with the commercial AD6645ASTZ in flight hardware - the commercial-grade part lacks MIL-PRF-38535 Class V screening, lot traceability, and the 100 krad(Si) radiation rating. Also confirm the SMD revision letter on each shipment matches the qualified parts list; revision drift between lots can change pin assignments per the SMD 5962R04230 drawing. Reference: SMD database at ddc-web.com and MIL-STD-38535.
Datasheet guidance: drive ENCODE and ENCODE_BAR differentially for jitter < 0.2 ps RMS - the analogue input bandwidth of the AD6645 die is broad, but achievable SNR depends on aperture jitter; aim for source-synchronous driver with a CDN > 50 dB at 5 × fin. Use a 4-layer FR4 (or, for full MIL-spec stacks, polyimide) with controlled-impedance 50-Ω input trace to preserve SINAD and SFDR at full rate. Reference: AD6645 datasheet jitter specification.
