Application Information

The TQMC700 is a VITA93.0 compatible single-width

QMC offering a user programmable AMD Artix 7 7A50T

FPGA.

The TQMC700 provides 16 ESD-protected 5V-tolerant

TTL lines. All I/O lines are individually programmable as

input or output. TTL I/O lines can be set to high, low, or

tristate. Each TTL I/O line has a pull-resistor to a common

programmable pull-up voltage that can be set to +3.3 V,

+5 V and GND.

The 18 bit ADC offers 8 input channels, each of them has

a sampling rate of up to 1 Msps. Each channel can be

operated in bipolar single-ended, unipolar single-ended

and bipolar differential mode. In the single-ended modes it

offers software selectable input voltage ranges of 0-5 V, 0

10 V, 0-12.5 V, ±2.5 V, ±5 V, ±6.25 V, ±10 V and ±12.5V.

In differential mode the input voltages are selectable

between ±5 V, ±10 V, ±12.5 V and ±20 V. There is a

flexible digital filter offering a oversampling ratio up to 256.

The DAC offers 4 channels of 16 bit analog outputs with

software selectable output voltage ranges of 0-5 V, 0-10

V, 0-10.8 V, ±5 V, ±10 V or ±10.8 V. The output voltage

range can be individually set per channel. The conversion

time is typ. 10 μs and the DAC outputs are capable to

drive a load of 2 kΩ, with a capacitance up to 4000 pF.

Each TQMC700 is factory calibrated. The calibration

information is stored in an on-board serial EEPROM

unique to each TQMC700 module.
