1 Introduction

The ADCxxDJxx00RFEVM/SEEVM is an evaluation board used to evaluate the ADC12DJ5200RF, ADC12DJ4000RF, ADC08DJ5200RF, ADC12DJ5200SE analog-to-digital converters (ADC) from Texas Instruments. The ADC12DJ5200RF and SE is a dual-channel, 12/08-bit ADC, capable of operating at sampling rates up to 5.2 and 4 Giga-samples per second (GSPS) in dual-channel mode, or 10.4 and 8 GSPS in single-channel mode. The ADC12DJ5200RF/SE, ADC12DJ4000RF, ADC08DJ5200RF output data is transmitted over a standard JESD204C high-speed serial interface. This evaluation board also includes the following important features:

• Transformer-coupled signal input network allowing a single-ended signal source from 500 kHz to
  9 GHz. ADC12DJ5200SE has an internal balun in the ADC chip.
• The LMX2594 clock synthesizer generates the ADC sampling clock
• The LMK04828, LMK61E2 and LMX2594 onboard system clock generator generates SYSREF and FPGA reference clocks for the high-speed serial interface
• Transformer-coupled clock input network to test the ADC performance with an external low-noise clock source
• LM95233 temperature sensor
• High-speed serial data output over a High Pin Count FMC+ interface connector
  Note:

  To improve signal routing quality, serial lane polarity is inverted with respect to the standard FMC VITA-57 signal mapping. Signal mapping and polarity is shown in Table 8-1).

• Device register programming through USB connector and FTDI USB-to-SPI bus translator

The digital data from the ADCxxDJxx00RFEVM/SEEVM board is quickly and easily captured with the TSW14J57EVM data capture boards.

The TSW14J57EVM captures the high-speed serial data, decodes the data, stores the data in memory, and then uploads it to a connected PC through a USB interface for analysis. The High-Speed Data Converter Pro (HSDC Pro) software on the PC communicates with the hardware and processes the data.

With proper hardware selection in the HSDC Pro software, the TSW14J57 device is automatically configured to support a wide range of operating speeds of the ADCxxDJxx00RFEVM/SEEVM, but the device may not cover the full operating range of the ADC device. Serial data rates of 15 Gbps down to 1 Gbps are supported.
