Texas Instruments WV4ADCIFCABLE

Overview

WV4ADCIFCABLE from National Semiconductor is a USB 2.0 interface cable designed exclusively for the WaveVision4 Data Capture Board, enabling high-speed data transfer between the board and Windows XP/2000 host PCs during ADC/DAC evaluation. It supports full-speed USB 2.0 (USB 1.1 in version 4), delivers plug-and-play connectivity without jumpers, and is required for firmware upload, sample acquisition, and waveform download operations at up to 200 MHz sampling rates.

For engineers reviewing the WV4ADCIFCABLE datasheet, WV4ADCIFCABLE pinout, WV4ADCIFCABLE application, or WV4ADCIFCABLE equivalent, this cable is essential for establishing reliable host-to-capture-board communication in analog converter test setups - particularly when performing FFT analysis, histogram generation, or synchronized DAC waveform playback using National Semiconductor's evaluation ecosystem.

Technical Context

The WV4ADCIFCABLE serves as the sole physical link between the host PC and the WaveVision4 Data Capture Board's J2 (USB) connector. It carries standard USB 2.0 signals - D+, D−, VBUS (+5 V), and GND - and is certified for full-speed (12 Mbps) operation in WaveVision4 v4 and high-speed (480 Mbps) in v4.1. No signal conditioning, termination, or protocol translation is performed within the cable itself.

This cable operates strictly as a passive interconnect: it does not contain active components, voltage regulation, or ESD protection circuitry. Its functionality is fully dependent on the host-side USB controller, the WaveVision4 board's U24 USB microcontroller, and correct driver installation under Windows XP/2000. No firmware or configuration resides in or is loaded via the cable.

Key Specifications

Manufacturer

National Semiconductor was a U.S.-based semiconductor company specializing in analog and mixed-signal ICs, acquired by Texas Instruments in 2011. It pioneered high-performance data converter evaluation platforms.

The WV4ADCIFCABLE belongs to the WaveVision4 evaluation system product line, engineered specifically to enable seamless USB-based control and data exchange between host PCs and National Semiconductor's ADC/DAC evaluation boards - eliminating manual jumper configuration and accelerating time-to-test.

FAQ

Is WV4ADCIFCABLE a standard USB cable, or does it have custom wiring?

WV4ADCIFCABLE is a standard USB 2.0 Type-A to Type-B cable with no custom pinout or internal circuitry. However, it is factory-qualified and shipped as part of the official WaveVision4 kit (order number WAVEVSN BRD 4.1). While electrically identical to compliant off-the-shelf cables, National Semiconductor validated its performance for firmware loading, clock synchronization, and sustained 200 MHz data capture - making it the recommended and supported interconnect for WV4ADCIFCABLE-dependent operations.

Can WV4ADCIFCABLE be used with WaveVision3 or earlier systems?

No. WV4ADCIFCABLE is designed exclusively for the WaveVision4 Data Capture Board's J2 (USB) interface. WaveVision1/2/3 systems use RS-232 serial interfaces and incompatible connectors. Attempting to use WV4ADCIFCABLE with legacy capture hardware will not establish communication - the WaveVision4 software explicitly requires USB enumeration via the U24 microcontroller present only on the WaveVision4 board, which is absent in prior generations.

Does WV4ADCIFCABLE provide power to the WaveVision4 board?

Yes. WV4ADCIFCABLE delivers +5 V (VBUS) from the host PC to the WaveVision4 Data Capture Board through the J2 USB connector. This is sufficient to power the board (rated at ~200 mA) when no external supply is connected to J1. However, ADC/DAC evaluation boards often require additional power sources - WV4ADCIFCABLE does not supply auxiliary voltages (e.g., +3.3 V, +2.5 V) or current beyond USB specification limits.

What happens if I substitute a third-party USB cable for WV4ADCIFCABLE?

Substitution may result in failed firmware uploads, dropped samples during acquisition, or inability to enter IDLE mode (LED4 off). Although electrically similar, non-qualified cables can introduce timing jitter or impedance mismatches that disrupt the precise USB handshake required by the U24 microcontroller and FPGA configuration sequence. National Semiconductor's validation ensures consistent enumeration and bulk-transfer reliability - critical for WV4ADCIFCABLE's role in ADC clock measurement and SRAM upload phases.

Is WV4ADCIFCABLE required for DAC waveform playback functionality?

Yes. WV4ADCIFCABLE is mandatory for all host-initiated operations on the WaveVision4 system, including DAC waveform download. The WaveVision4 software sends waveform data (Sine, Triangle, Pulse, etc.) from the PC to the USB microcontroller (U24), then to the FPGA and SRAM - a path that depends entirely on the bidirectional USB link provided by WV4ADCIFCABLE. Without it, no waveform data can be loaded, and DAC output remains inactive.
