5-GSPS Dual DAC FMC Module, FMC2657

FMC2657 – 5-GSPS 12-bit Dual DAC FMC Module
PRODUCT DESCRIPTION
The FMC2657 module is equipped with two Euvis MD657B digital-to-analog converters(DAC’s). At 5 GSPS, the module provides analog outputs with bandwidth from DC to 2.5
GHz (Nyquist bandwidth). It can be selected to operate in return-to-zero mode to extend theusable bandwidth to 2.5 ~ 5 GHz. The 96 LVDS pairs of digital data are fed through twoFMC connectors, a high-pin-count (HPC) and a low-pin-count (LPC) connector. The digital
data multiplexing ratio is 4:1 and the digital data rate is 1.25 GBPS with the DAC'soperating at 5 GSPS. Sampling window select (SEL’s), Return-to-Zero select, and reset
signals of the two DAC’s can be independently controlled via the FMC connectors. The
module includes two clock buffers to relax the need of high-power clock source. Bothamplitudes and duty cycles of clock buffers can be programmed though I2C interface or use
factory preset values.

Normal operation has usable bandwidth from DC to Nyquist bandwidth, 2.5GHz, at 5 GSPS.
In return-to-zero(RZ) mode, the usable bandwidth can be DC ~ 2.5 GHz and 2.5 ~ 5 GHz.
2If external 50-ohm loads are terminated to ground, the analog outputs will
have voltage swings from ground to – 0.6 V with a common mode voltageof –0.3 V. If a positive analog output common mode level is desired, theexternal 50 ohm loads can be terminated to a positive voltage Vpull with aresultant analog output common mode voltage of (Vpull – 0.6)/2.
Vpull should not exceed 5 V.

TEST SETUP
In applications, FMC2657 requires a VITA 57.1-compliant carrier board to provide all
digital data, DAC controls, I2C signal, and DC powers via FMC connectors. The carrier
must provide two power supplies, +12V and +3.3V, with minimum current capacities of 1Aand 500mA respectively. Digital data and DAC resets are in LVDS pairs. The DAC timing
selects and return-to-zero mode select are single-ended LVCMOS25. The carrier board canbe an advanced FPGA evaluation board, such as Xilinx VC707, with proper configurations.
The FMC module is tested using Euvis carrier FMCC371 as shown in following figure. Thecarrier consists of a Xilinx XC6VLX130T, a USB controller, and power modules. In the test
setup, the carrier is controlled by a PC host via the USB interface. The carrier can store upto 2 x 512 K words of data in memory. The maximum data length is 64us at 4 GSPS foreach channel. Several built-in waveforms are available as in our AWG’s GUI. Waveformgeneration and download are performed in GUI.
