5-GSPS Single DAC FMC Module, FMC1657

FMC1657 – 5-GSPS 12-bit Single DAC FMC Module
PRODUCT DESCRIPTION
The FMC1657 module is equipped with an 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 48 LVDS pairs of digital data are fed through a FMC
connector, a high-pin-count (HPC) connector. The digital data multiplexing ratio is 4:1 andthe digital data rate is 1.25 GBPS with the DAC's operating at 5 GSPS. Sampling window
select (SEL’s), Return-to-Zero select, and reset signals of the DAC’s can be independently
controlled via the FMC connector. The module includes a clock buffer to relax the need ofhigh-power clock source. Both amplitude and duty cycle of the clock buffer can be
programmed though I2C interface or use factory preset values.

1Normal operation has usable bandwidth from DC to Nyquist bandwidth, 2.5 GHz, 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.
