CLC5958SLB Overview
An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples continuous-time analog voltages and converts each sample into a discrete digital code. Within the broader signal-chain taxonomy, the CLC5958SLB belongs to the high-speed pipelined ADC family, which sits between successive-approximation-register (SAR) ADCs (typically <5 MSPS) and flash or folding ADCs (typically >100 MSPS). Pipelined ADCs are the workhorse of communications, radar, and instrumentation receivers in the 10 MSPS to 250 MSPS range because they balance conversion speed, resolution, and power dissipation. The CLC5958SLB targets the 14-bit tier of this family, which is widely used in cellular base-station receivers, cable modem upstream paths, and medical imaging front-ends.
Key features include a sampling rate up to 52 MSPS, 14-bit resolution with no missing codes, and an input bandwidth suitable for IF undersampling. The 48-PLGA package provides low thermal resistance and accommodates the exposed thermal pads required for reliable operation at full speed. The device supports industrial operating temperatures from -40C to +85C and is offered in tube packaging for production assembly lines.
Typical applications include wideband communications receivers, IF sampling for software-defined radio (SDR), medical ultrasound beamformers, and high-performance instrumentation. The combination of speed, resolution, and the compact PLGA package makes it suitable for both laboratory and field-deployed equipment.
When designing with this part, provide separate analog and digital ground planes connected at a single point, place the input anti-aliasing filter close to the analog input pin, and ensure the exposed thermal pads are soldered to a sufficient copper pour to maintain junction temperature within datasheet limits under continuous operation.

Typical Applications
CLC5958SLB is suitable for 6 applications: Wideband Communications Receiver, Software Defined Radio (SDR) IF Sampling, Medical Ultrasound Beamforming, High-Performance Test & Measurement Instrumentation, Radar Signal Processing Front-End, Industrial Process Control Data Acquisition.
Wideband Communications Receiver
The CLC5958SLB's 14-bit resolution at 52 MSPS makes it a strong fit for wideband communications receivers that must digitize IF signals cleanly. It is commonly placed after a front-end mixer and anti-aliasing filter, sampling the IF directly to simplify the analog chain. The pipelined architecture delivers the SFDR needed for cellular base-station receivers, cable modem upstream paths, and microwave-link IF strips. Designers should route the analog input traces as a 100 ohm differential pair and decouple the analog supply close to the AVDD pin to preserve SNR at full speed.
Recommended
Software Defined Radio (SDR) IF Sampling
The CLC5958SLB suits SDR IF sampling chains where a wide instantaneous bandwidth and clean digitization are required. Its 52 MSPS sampling rate comfortably covers IF frequencies up to 25 MHz while meeting the SFDR requirements of modern digital demodulators. Combined with a high-performance FPGA, the parallel CMOS outputs feed directly into the FPGA's LVCMOS receive registers without an external buffer. The exposed thermal pad of the 48-PLGA package keeps the junction temperature under control when the device runs continuously at full sample rate in a thermally-constrained SDR enclosure.
Recommended
Medical Ultrasound Beamforming
Ultrasound front-ends digitize returning acoustic echoes at high sample rates while preserving dynamic range, and the CLC5958SLB's 14-bit / 52 MSPS combination fits portable cart-based ultrasound systems. The pipelined core provides the linearity needed to detect small echoes next to large reflectors, improving image contrast. Differential analog inputs reject common-mode noise injected by nearby RF transmitters in the probe assembly. The 48-PLGA package and exposed thermal pad suit dense multi-channel beamformer boards where several ADCs operate in parallel.
Recommended
High-Performance Test & Measurement Instrumentation
Bench-top digitizers, spectrum analyzers, and arbitrary waveform recorder modules benefit from the CLC5958SLB's combination of 14-bit resolution, 52 MSPS throughput, and parallel output interface. The ADC samples conditioned analog signals at full Nyquist or IF under-sampling rates while preserving SFDR above 70 dBFS. Its parallel data bus simplifies FPGA-based capture logic, allowing deep memory captures without an external deserializer. The industrial -40C to +85C temperature range and exposed thermal pad support laboratory and field-deployed instrumentation enclosures.
Recommended
Radar Signal Processing Front-End
Radar IF and baseband digitization chains require wide bandwidth and clean dynamic range, both of which the CLC5958SLB delivers at 52 MSPS. The pipelined architecture handles pulsed-Doppler and FMCW return signals with the linearity needed for accurate target detection. The parallel digital output supports direct connection to FPGAs running FFT and pulse-compression algorithms. The exposed thermal pad ensures reliable operation in rugged outdoor radar enclosures operating across the industrial temperature range.
Recommended
Industrial Process Control Data Acquisition
Industrial data-acquisition systems digitize multiple sensor signals at moderate speeds for process monitoring and control. The CLC5958SLB's 52 MSPS sampling rate and 14-bit resolution suit high-speed vibration analysis, acoustic emission monitoring, and power-line transient capture. The single-ended-to-differential input simplifies interface with industrial sensors using instrumentation amplifiers. The wide -40C to +85C operating range tolerates factory-floor thermal swings while the 48-PLGA package suits compact DAQ module designs.

- Parallel CMOS digital output (vs LVDS-serial-output 14-bit ADCs)
Design Notes
Use separate analog and digital ground planes on the CLC5958SLB board, joined at a single point under or near the ADC. Place the input anti-aliasing filter within 5 mm of the analog input pins and route the analog inputs as a 100 ohm differential pair with controlled impedance. The exposed thermal pad of the 48-PLGA package must be soldered to a copper pour of at least 1 square inch to keep junction temperature within limits at 52 MSPS continuous operation.
The CLC5958SLB requires separate analog (+5V) and digital (+3.3V) supplies. Decouple each supply pin with a 100 nF ceramic capacitor placed within 2 mm of the pin, plus a 10 uF bulk capacitor on each rail. Use a ferrite bead or small series resistor between the analog and digital 5V rails if they derive from a common source, to prevent digital switching noise from corrupting the analog reference. Verify supply sequencing: power up the analog supply before the digital supply to avoid latch-up.
Drive the CLC5958SLB clock input with a low-jitter, fast-edge source - a CMOS clock buffer placed within 25 mm of the clock pin is recommended. Excessive clock jitter (>5 ps RMS) directly degrades SNR at the analog input. Terminate the parallel digital output traces with 33 ohm series resistors placed near the ADC to damp reflections into the FPGA. Keep digital output traces short and avoid routing them parallel to the analog input traces.
Do not assume any 14-bit 52 MSPS ADC is a drop-in replacement for the CLC5958SLB - the 48-PLGA pinout is specific to this part family. Cross-brand alternatives (e.g. AD9640, ADS6445) come in different packages and require PCB rework. Because the part is NRND, confirm long-term availability before committing to a new design; for new designs consider modern 14-bit ADC families with active lifecycle status.
Compliance Information
Compliance data was not present in the verified web snippets; RoHS, REACH, lead-free, and halogen-free status are unknown. The CLC5958SLB is an industrial-grade part, not automotive-qualified (AEC-Q100 not applicable).
