Model VM8DAC
Low Noise
Digital to Analog Converter
8 Channel VME Module
VM8DAC VMEbus digital to analog converter
(DAC) boards from Frequency Devices Inc. offer
eight channels of precision low distortion/low
noise, digital to analog converters that operate
with a sample clock frequency derived from a
master external clock and a programmable time
base divider. The boards are available in a single
width B-size (6U) VME form factor that conforms
to VMEbus Revision C.1 as an A32/D32 Data
Transfer Bus Slave.
VM8DAC boards provide high (24-bit) and low
(16-bit) resolution data access to on-board
DAC’s. The boards interpret the received parallel
data from the VMEbus as binary-2’s complement.
This data is serialized and transferred to any
selected DAC channel at a fixed master time
base where it is converted to analog signals at a
software programmable sampling rate. The DAC
channels may be configured to 16,384, 8,192,
4,096, or 2,048 samples per second.
Features/Benefits
•
Eight discrete channels with programmable
sampling that provide a 24- bit DAC stage for
each channel offers the user versatile and
convenient digital to analog conversion.
Outputs synchronized to the front panel
external
clock
allow
for
multi-card
synchronicity.
Designed for Real Time Operating Systems
(RTOS) to provide minimal pipeline delay
(less than 5 microseconds). i.e. Linux or Vx
Works.
Interrupt free operation provides glitch energy
of <5nV-sec and extremely low noise density
(ï100nV/
Hz
).
VME backplane is galvanically isolated from
the analog section to reduce system
integration problems.
