D/A PMC Module includes FIFOs.

Press Release Summary:



Providing 32 or 16 channels of 16-bit analog outputs, single-wide 32-bit Model TPMC554 features software selectable output voltages of 0-5, 0-10, 0-10.8, ±5, ±10, or ±10.8 V and can be individually set per channel. Conversion time is typically 10 µs and DAC outputs can drive load of 2 kW, with capacitance up to 4,000 pF. In addition to double buffered distributed RAM inside FPGA, TPMC554 provides 2 M x 16-bit external SRAM to store values that are known in advance.

Tews Technologies Introduces New High-Density 16-bit D/A PMC Module with FIFOs



TEWS TECHNOLOGIES today announced the TPMC554, a new high-density 16-bit D/A PMC Module with FIFOs, for its expanding line of PMC modules. The standard single-wide 32-bit PMC module provides 32 or 16 channels of 16-bit analog outputs. The TPMC554 is ideal for applications in industrial, transportation, and COTS aerospace/defense.
The software selectable output voltage ranges are 0-5V, 0-10V, 0-10.8V, ±5V, ±10V or ±10.8V and can be individually set per channel. The conversion time is typically 10 µs and the DAC outputs are capable to drive a load of 2kohm, with a capacitance up to 4000pF.

The double buffered DACs allow simultaneous update of all channels for simulation applications. A sequencer on the TPMC554 supports the periodic updating of enabled channels with a sequence timer range from 10µs to 11.93h.

In addition to the double buffered distributed RAM inside the FPGA, the TPMC554 provides 2 M x 16-bit external SRAM to store values that are known in advance. This feature can also be used to periodically output any kind of waveform or bit pattern. The size of the FIFO for each DAC channel is adjustable.

Physical connectivity is achieved through a HD68 SCSI 3 type front I/O connector.
Each TPMC554 is factory calibrated. The calibration information is stored in an on board serial EEPROM unique to each PMC module.

The TPMC554 operates in extended temperature range (-40°C to +85°C) standard. All TEWS TECHNOLOGIES products feature a five-year warranty.

TEWS believes in a total solution philosophy. As a result, we offer driver software for our modules for operating systems including VxWorks, Windows, Linux, LynxOS, Integrity and QNX6.
