Renesas KDC5512EVAL

Overview

KDC5512EVAL from Renesas Electronics is an evaluation system motherboard designed to characterize high-speed analog-to-digital converters (ADCs) in the 8-bit to 16-bit, 40MSPS to 500MSPS range. It hosts daughter cards such as the KDC2710 and supports real-time spectral analysis via USB2.0 interface, 18Mb FIFO buffer, and Intersil Konverter Analyzer software for SFDR, SINAD, ENOB, and harmonic measurements.

For engineers reviewing the KDC5512EVAL datasheet, KDC5512EVAL pinout, KDC5512EVAL application, or KDC5512EVAL equivalent, this platform enables rapid ADC performance validation with live time-domain and frequency-spectrum visualization, low-jitter signal/clock interfacing (≤200fs combined), and Windows XP/2000 compatibility - critical for RF, communications, and test instrumentation design.

Technical Context

The KDC5512EVAL serves as a universal motherboard for Renesas' FemtoCharge™-based ADC daughter cards, providing regulated supply voltages, digital data capture logic, and clock conditioning circuitry. It interfaces with ADCs via a mezzanine connector and routes analog inputs and sampling clocks through SMA connectors with impedance-matched traces.

Its USB2.0 interface handles high-throughput streaming of digitized samples (up to 500MSPS raw data rates), while the 18Mb FIFO buffers 1M samples for offline analysis. The system requires external 5V/4W power and relies on host PC-based MATLAB Component Runtime (MCR v7.6 or v7.13) for Konverter Analyzer operation.

FAQ

What is the KDC5512EVAL used for?

The KDC5512EVAL is a dedicated evaluation motherboard that enables functional and dynamic performance testing of Renesas' high-speed ADC daughter cards (e.g., KDC2710). It provides power regulation, digital data capture, USB2.0 streaming, and SMA-based analog/clock interfaces - all required to measure SFDR, SINAD, ENOB, and harmonic distortion per IEEE Std 1057. The KDC5512EVAL itself contains no ADC; it must be paired with a compatible daughter card to form a complete evaluation platform.

Which ADC daughter cards are compatible with the KDC5512EVAL?

The KDC5512EVAL is mechanically and electrically compatible with Renesas' KMB001-family ADC daughter cards, including the KDC2710 and other 8-bit to 16-bit, 40MSPS to 500MSPS converters using the same mezzanine connector footprint and signal mapping. Compatibility is confirmed in AN1434 Rev 4.00, which explicitly references KDC2710 integration and lists the KDC5512EVAL as part of the KMB001 evaluation system architecture.

Does the KDC5512EVAL include ADC conversion functionality?

No - the KDC5512EVAL is a motherboard-only platform and does not contain an integrated ADC. All analog-to-digital conversion is performed by the plug-in daughter card (e.g., KDC2710). The KDC5512EVAL provides power sequencing, clock distribution, digital data capture, FIFO buffering, and USB2.0 interface logic to support and stream output from the daughter card's ADC core.

What software is required to operate the KDC5512EVAL?

The KDC5512EVAL requires the Intersil Konverter Analyzer software (v1.15.6c or later), which runs on Windows XP or Windows 2000 and depends on MATLAB Component Runtime (MCR v7.6 or v7.13). The software displays real-time FFT spectra, time-domain waveforms, and computed metrics including SFDR, SINAD, ENOB, and harmonic amplitudes - all derived from digitized samples captured by the KDC5512EVAL.

What are the signal and clock source requirements for accurate KDC5512EVAL measurements?

For optimal dynamic performance, AN1434 specifies ≤200fs combined jitter across both signal and clock sources. Clock input must be a 50MHz–500MHz sine wave at +10dBm; analog input must be 0.4MHz–250MHz at +7dBm to +10dBm (adjustable via onboard attenuation). These constraints ensure minimal aperture jitter and SNR degradation when evaluating ADCs using the KDC5512EVAL platform.
