Renesas KDC5512-Q48EVAL

Overview

KDC5512-Q48EVAL from Renesas Electronics is an evaluation platform motherboard designed to characterize 8-bit to 16-bit, 40MSPS to 500MSPS analog-to-digital converters (ADCs) using Intersil's FemtoCharge™ technology. It supports live spectral analysis (SFDR, SINAD, ENOB), captures 1M samples via 18Mb FIFO, and interfaces via USB 2.0 to Windows XP/2000 PCs for real-time ADC performance validation in high-speed data acquisition systems.

For engineers reviewing the KDC5512-Q48EVAL datasheet, KDC5512-Q48EVAL pinout, KDC5512-Q48EVAL application, or KDC5512-Q48EVAL equivalent, this page delivers verified technical context, key specifications, supply support, and manufacturer-specific design intent - all grounded in the official AN1434 Rev 4.00 user manual and Renesas' documented ADC evaluation system architecture.

Technical Context

The KDC5512-Q48EVAL is a fixed-configuration evaluation motherboard - not a daughter card - and serves exclusively as the host platform for interchangeable ADC daughter cards (e.g., KDC2710). It provides regulated power rails, clock conditioning, analog input SMA connectors, and digital capture logic synchronized to the ADC's sampling clock.

It integrates a 18Mb FIFO buffer, USB 2.0 interface controller, and firmware-level timing alignment to minimize aperture jitter impact during FFT-based measurements. System-level operation requires the Intersil Konverter Analyzer software (v1.20c+ with MATLAB Component Runtime 7.13) for real-time spectral plotting, harmonic analysis, and ENOB/SINAD/SFDR computation.

FAQ

What is the primary function of the KDC5512-Q48EVAL?

The KDC5512-Q48EVAL is a motherboard-only evaluation platform that hosts interchangeable ADC daughter cards. It provides power regulation, clock distribution, analog signal routing, and high-speed digital capture via an 18Mb FIFO and USB 2.0 interface - enabling engineers to measure SFDR, SINAD, ENOB, and harmonic distortion of supported 8-bit to 16-bit, 40MSPS–500MSPS ADCs. The KDC5512-Q48EVAL itself contains no ADC core.

Which operating systems are officially supported for the KDC5512-Q48EVAL?

The KDC5512-Q48EVAL requires Microsoft Windows XP or Windows 2000 with administrator rights, a free USB 2.0 port, and minimum 512MB RAM (1024MB recommended). It is incompatible with Windows Vista or later versions per AN1434 Rev 4.00. The Intersil Konverter Analyzer software (v1.20c+) and MATLAB Component Runtime 7.13 must be installed separately - both are validated only on these two OS versions.

Does the KDC5512-Q48EVAL include an ADC or require a separate daughter card?

The KDC5512-Q48EVAL does not contain an ADC. It is a motherboard-only platform that requires a compatible ADC daughter card (e.g., KDC2710) to be mounted via its mezzanine connector. All ADC functionality - including sampling, analog front-end, and digital output - resides solely on the daughter card. The KDC5512-Q48EVAL provides power, clock, signal routing, and data capture infrastructure.

What software is required to operate the KDC5512-Q48EVAL?

Operation of the KDC5512-Q48EVAL requires the Intersil Konverter Analyzer software (v1.20c or later) and MATLAB Component Runtime 7.13. The software performs real-time FFT analysis, displays frequency spectra and time-domain waveforms, and computes SFDR, SINAD, ENOB, and harmonic content. Both components must be downloaded from the Renesas website and installed in sequence - earlier versions must be uninstalled first.

What are the critical signal source requirements for accurate KDC5512-Q48EVAL measurements?

For valid ENOB and SFDR results, the KDC5512-Q48EVAL requires combined clock + signal source jitter ≤200fs RMS. The clock input must be a 50MHz–500MHz sine wave at +10dBm; the analog input must be 0.4MHz–250MHz at +7dBm to +10dBm (depending on attenuation setting). These constraints ensure aperture jitter and noise contributions remain below measurement floor thresholds defined in AN1434.
