The ADAC250 FPGA mezzanine card (FMC)

is designed around the high-performance

A/D and D/A conversion technology from

Texas Instruments — it integrates one dual, 14-bit,

250 MSPS analog-to-digital converter (ADS62P49)

and a dual, 16-bit, 1 GSPS digital-to-analog

converter (DAC5682Z; also capable of a 2–4×

interpolation mode). Combined with multiple

clocks and synchronization modes, the ADAC250

is at its best in DSP applications such as software-

defined radio (SDR), advanced telecommunications

(MIMO systems, cognitive radios, beamformers,

LTE, WiMAX), signal intelligence (SIGINT), radar,

sonar, and medical imaging applications.

The ADAC250 uses the VITA 57.1 standard, widely

used in the digital signal processing industry, which

makes it easier for developers to integrate FPGAs

into their embedded system designs. The FMC is

completely Plug & Play with our μTCA Perseus AMCs, but

the ADAC250 can as easily be used on any FMC carrier out

there.

Hardware architecture

The VITA 57.1 (FMC) standard comes to the rescue of

complex designs with its unprecedented mechanical and

electrical flexibility — VITA 57.1 provides a standard

specification for small mezzanine modules designed

to adapt an FPGA-based carrier card to different I/O

requirements.

Clock management facility

The ADAC250’s clock management facility is designed

around the

low phase noise clock distribution, a bypassable PLL core,

bypassable dividers, and the possibility to adjust the phase

of five clock outputs. Combining the clock management

facility to the very-low-jitter 4×4 crosspoint switch makes

it possible to generate the sampling clock of the ADAC250

several different ways:

16-bit interleaved I/Q or dual-channel mode

Equipped with an onboard, low-jitter reference clock

and synchronization PLL (AD9511).

Supports external or FMC-driven reference clocks for

synchronized multiboard/multichannel applications.

Supports external or FMC-driven sampling clocks

(AD9511 with the PLL bypassed) for phase-coherent

multiboard/ multichannel applications.

Supports external triggers for event-based acquisition.
