Renesas KDC5512-50EVAL

Overview

KDC5512-50EVAL from Renesas Electronics is an evaluation system 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 labs.

For engineers reviewing the KDC5512-50EVAL datasheet, KDC5512-50EVAL pinout, KDC5512-50EVAL application, or KDC5512-50EVAL equivalent, this platform enables rapid, repeatable ADC characterization with calibrated signal/clock input paths, on-board power regulation, and Konverter Analyzer software integration - critical for RF receiver, test instrumentation, and radar subsystem development.

Technical Context

The KDC5512-50EVAL serves as a universal motherboard for interchangeable daughter cards hosting discrete ADCs (e.g., KDC2710). It provides regulated supply voltages, clock distribution, analog input conditioning, and digital capture logic - all synchronized to external 50MHz–500MHz sampling clocks and 0.4MHz–250MHz analog signals.

Its architecture separates signal path integrity (SMA-connected analog input and clock inputs) from digital interface (USB 2.0) and processing (host PC running Konverter Analyzer). The system requires ≤200fs combined clock+signal jitter to preserve ENOB and SFDR measurements per IEEE Std 1241.

FAQ

What is the primary function of the KDC5512-50EVAL?

The KDC5512-50EVAL is an evaluation motherboard that hosts interchangeable ADC daughter cards (e.g., KDC2710) to validate 8-bit to 16-bit, 40MSPS to 500MSPS analog-to-digital converters. It provides regulated power, clock distribution, analog signal conditioning, and USB 2.0 data capture - enabling full spectral and time-domain characterization of ADC performance using Konverter Analyzer software. The KDC5512-50EVAL itself contains no ADC; it is strictly a test platform.

Which ADC daughter cards are compatible with the KDC5512-50EVAL?

The KDC5512-50EVAL is mechanically and electrically compatible with Intersil/Renesas ADC daughter cards using the same mezzanine connector interface, including KDC2710 and other members of the KDCxxx series. Compatibility depends on matching pinout, voltage rail requirements, and clock interface type (LVDS/CMOS). Users must verify mechanical fit and signal integrity per AN1434 Rev 4.00; no automatic compatibility is guaranteed across all variants.

Does the KDC5512-50EVAL include ADC conversion functionality onboard?

No - the KDC5512-50EVAL is a motherboard-only platform with no integrated ADC. All analog-to-digital conversion occurs on removable daughter cards (e.g., KDC2710) that plug into its mezzanine socket. The KDC5512-50EVAL provides power regulation, clock buffering, analog input termination, and digital data capture logic - but zero signal conversion capability resides on the motherboard itself.

What software is required to operate the KDC5512-50EVAL?

The KDC5512-50EVAL requires Intersil Konverter Analyzer software (v1.20c or later), which runs on Windows XP or Windows 2000 with ≥512MB RAM and SSE2-capable CPU. It also requires MATLAB Component Runtime (MCR) v7.13 and the Renesas-provided USB driver. The KDC5512-50EVAL does not function with generic USB oscilloscope or data acquisition software - only Konverter Analyzer provides correct register access, FFT computation, and ENOB/SFDR reporting.

What are the signal source requirements for accurate KDC5512-50EVAL measurements?

For valid KDC5512-50EVAL measurements, the analog input signal must be 0.4MHz–250MHz at +7dBm to +10dBm (adjusting for attenuation), and the sampling clock must be 50MHz–500MHz sine wave at +10dBm. Combined clock+signal jitter must not exceed 200fs RMS to prevent aperture jitter-induced ENOB degradation - verified using low-phase-noise synthesizers and precision SMA cabling per Appendix A of AN1434.
