Hi,
Customer needs the documents as below for customs clearance.
Per customer:
We require supporting documents in relation to or stating
the following specifications for product, Analog Devices AD5392 8-channel,
14-bit voltage output DAC:
a)'adjusted update rate' (in mega samples per second (MSPS));
b)'Spurious Free Dynamic Range' (SFDR) (in dBc) (carrier) when
synthesising a full scale analogue signal of 100 MHz or the highest full
scale analogue signal frequency specified below 100 MHz.
Technical Notes
1.'Spurious Free Dynamic Range' (SFDR) is defined as the ratio of the rms
value of the carrier frequency (maximum signal component) at the input of
the DAC to the rms value of the next largest noise or harmonic distortion
component at its output.
2.SFDR is determined directly from the specification table or from the
characterisation plots of SFDR versus frequency.
3.A signal is defined to be full scale when its amplitude is greater than
-3 dBfs (full scale).
4.'Adjusted update rate' for DACs:
a)For conventional (non-interpolating) DACs, the 'adjusted update rate' is
the rate at which the digital signal is converted to an analogue signal
and the output analogue values are changed by the DAC. For DACs where the
interpolation mode may be bypassed (interpolation factor of one), the DAC
should be considered as a conventional (non-interpolating) DAC.
b)For interpolating DACs (oversampling DACs), the 'adjusted update rate'
is defined as the DAC update rate divided by the smallest interpolating
factor. For interpolating DACs, the 'adjusted update rate' may be referred
to by different terms including:
_input data rate
_input word rate
_input sample rate
_maximum total input bus rate
_maximum DAC clock rate for DAC clock input.
5.'Settling time' means the time required for the output to come within
one half bit of the final v"
Please help to advise whether can support.
Thanks
