CLC5955MTDX/NOPB Descripción general
Key specifications from the verified datasheet include 11-bit resolution, 55 MSPS sampling rate, single +5V supply, parallel output interface, and tape-and-reel packaging. The CLC5955 family has been designed as a monolithic broadband ADC providing high dynamic range and low power dissipation for communications infrastructure and instrumentation equipment.
The CLC5955MTDX/NOPB integrates a pipelined multi-stage converter architecture that internally calibrates gain and offset, achieving excellent linearity without external adjustment. The architecture delivers low-latency digital output suitable for real-time signal processing, while the parallel CMOS-compatible interface simplifies connection to FPGAs, ASICs, or DSP processors. The internal reference and sample-and-hold front-end support single-ended or differential analog inputs across a wide input bandwidth.
Typical applications include IF-sampled digital receivers in cellular base stations, broadband cable head-end equipment, test and measurement instrumentation such as digital oscilloscopes and spectrum analyzers, and radar/sonar digitizing front-ends. The wide dynamic range and high sampling rate also support medical imaging and software-defined radio platforms where capturing modulated IF signals with high spurious-free dynamic range is essential.
When designing with this device, allocate adequate decoupling on the +5V analog supply (typically 0.1uF ceramic plus 10uF tantalum close to the AVCC pins) and provide a low-impedance analog input driver with sufficient bandwidth to settle within half an LSB at the 55 MSPS clock rate. Route the parallel output bus with matched trace lengths to avoid setup-and-hold violations at downstream FPGAs.

Aplicaciones típicas
CLC5955MTDX/NOPB es adecuado para 6 aplicacións: IF-Sampled Digital Receiver, Test and Measurement Instrumentation, Software-Defined Radio (SDR) Platform, Radar and Sonar Digitizer, Medical Imaging Front-End, Industrial Process Control.
IF-Sampled Digital Receiver
The CLC5955MTDX/NOPB is the canonical IF-sampling ADC for cellular and broadband digital receivers, digitizing modulated IF carriers at 55 MSPS with 11-bit resolution to preserve dynamic range. The wide input bandwidth and pipelined low-latency output pair well with FPGA demodulators handling QAM/QPSK/OFDM waveforms, enabling a clean digital intermediate-frequency architecture in base stations and cable head-end equipment.
Recomendado
Test and Measurement Instrumentation
For digital oscilloscopes, spectrum analyzers, and arbitrary waveform digitizers, the CLC5955MTDX/NOPB delivers 55 MSPS at 11-bit resolution - sufficient for capturing repetitive transient waveforms and frequency-domain measurements up to 20 MHz. Its parallel CMOS interface streams conversion data directly into an FPGA buffer, supporting deep-memory capture while keeping the analog front-end simple with the device's internal sample-and-hold.
Recomendado
Software-Defined Radio (SDR) Platform
Software-defined radio platforms need a fast, wideband ADC that can digitize IF or even low-band RF directly into the FPGA signal-processing chain. The CLC5955MTDX/NOPB satisfies this with its 55 MSPS rate and 11-bit dynamic range, supporting real-time demodulation of narrowband and wideband signals across HF, VHF, and lower-UHF bands when paired with appropriate analog anti-alias filtering and an FPGA DSP core.
Recomendado
Radar and Sonar Digitizer
The CLC5955MTDX/NOPB fits radar and sonar digitizing front-ends that require moderate-resolution, high-speed conversion of wideband return signals. With 55 MSPS sampling and pipelined low-latency output, it provides the timing accuracy needed for pulse-compression and Doppler processing in marine sonar arrays, automotive radar modules, and surveillance radar IF strips where 11-bit dynamic range is adequate.
Recomendado
Medical Imaging Front-End
Medical ultrasound and digital X-ray imaging systems use the CLC5955MTDX/NOPB's 55 MSPS rate to digitize multi-channel transducer arrays at real-time frame rates. The pipelined architecture delivers consistent low-latency output essential for beamforming, while 11-bit dynamic range provides sufficient gray-scale resolution for diagnostic imaging in portable and bedside ultrasound equipment with strict thermal and footprint constraints.
Recomendado
Industrial Process Control
Industrial process control and factory automation systems use the CLC5955MTDX/NOPB to digitize high-speed sensor signals such as vibration, flow, and current transducers feeding PLCs or industrial PCs. The -40C to +85C industrial temperature grade handles harsh factory environments, and the parallel interface feeds data directly into FPGA-based motor-control loops running predictive maintenance and closed-loop process regulation algorithms.

Notas de diseño
Decouple AVCC and DVCC separately with 10uF tantalum in parallel with 0.1uF ceramic placed as close as practical to each supply pin. Because the CLC5955MTDX/NOPB samples at 55 MSPS, the high-frequency transients on the analog supply are significant - inadequate decoupling causes spurious tones in the digitized output. Add a ferrite bead between analog and digital +5V rails to further isolate the analog input sampling from digital switching noise.
Route the parallel CMOS data outputs with matched trace lengths (typically within 1-2 mm) to avoid setup-and-hold violations on the downstream FPGA or ASIC. Keep digital output traces well separated from the analog input traces to prevent digital switching noise from coupling into the high-impedance analog input - route them on opposite sides of the PCB and use a continuous ground plane as an RF shield between the two regions.
Drive the analog input with a low-impedance, broadband op-amp (such as a THS4631 or similar) capable of settling to 11-bit accuracy within the device's input bandwidth at 55 MSPS. The input sample-and-hold requires fast settling; insufficient input bandwidth limits spurious-free dynamic range. Use a differential drive configuration if the analog signal is single-ended, with the common-mode voltage set to mid-supply for optimal linearity.
