1 Introduction

The HSDC Pro GUI supports testing of all TI high-speed data converter EVMs when used with a TSW14xxx EVM. When used with an ADC EVM, high-speed data (either CMOS, LVDS, JESD204B serial, or JESD204C serial) is captured and then stored into a memory bank or directly inside the FPGA, depending on which TSW14xxx platform is being used. To acquire data on a host PC, the FPGA reads the data from memory and transmits it on Serial Peripheral Interface (SPI). An onboard high-speed USB-to-SPI converter bridges the FPGA SPI interface to the host PC and GUI.

In Pattern Generator Mode, HSDC Pro can generate the desired test patterns or load existing patterns for DAC EVMs under test. These patterns are sent from the host PC over the USB interface to the TSW14xxx. The FPGA stores the data received internally or into board memory, depending on the platform used. The data is then read by the FPGA and transmitted to a DAC EVM across the mating connector.

HSDC Pro GUI uses a DLL and a set of APIs to communicate from the GUI to the TSW14J5x via a Cypress FX3 USB 3.0 device. This next-generation USB 3.0 controller provides a programmable parallel interface which connects directly to the FPGA to provide high speed data transfers. The interface is compatible with both USB 2.0 and 3.0 systems. The theoretical limit for data transfer via USB 3.0 is 5Gbps and USB 2.0 is 480 Mbps. But with packet overhead and handshaking latency the effective throughput via the Cypress FX3 device is 2Gbps for USB 3.0 systems and 320 Mbps for USB 2.0 systems. The samples that are transferred to PC undergoes post processing and is stored as a binary file, due to which the effective data transfer rate is again reduced. With a 3.0 system, the user can capture 1 GBytes ≈ 20 seconds (400 Mbps). With a 2.0 system, around 45 seconds (177 Mbps). This controller is also used to configure the onboard FPGA using parallel programming mode, which allows for configuration in less than three seconds.

For the TSW1400 EVM, the GUI communicates via a FTDI FT4232H device. The FT4232H is a USB 2.0 Hi-Speed to UART IC. It has the capability of being configured in a variety of industry standards, such as serial or parallel interfaces. The FT4232H features 4 UARTs. Two of these have an option to independently configure an MPSSE engine, this allows the FT4232H to operate as two UART/Bit-Bang ports plus two MPSSE engines used to emulate JTAG, SPI, I2C, Bit-bang or other synchronous serial modes.
