Fusion Family of Mixed Signal FPGAs
Direct Digital Input
The AV, AC, and AT pads can also be configured as high-voltage digital inputs (Figure
As these
pads are 12 V–tolerant, the digital input can also be up to 12 V. However, the frequency at which these
pads can operate is limited to 10 MHz.
To enable one of these analog input pads to operate as a digital input, its corresponding Digital Input
Enable (DENAxy) pin on the Analog Block must be pulled High, where
x
is either V, C, or T (for AV, AC,
or AT pads, respectively) and
y
is in the range 0 to 9, corresponding to the appropriate Analog Quad.
When the pad is configured as a digital input, the signal will come out of the Analog Block macro on the
appropriate DAxOUTy pin, where
x
represents the pad type (V for AV pad, C for AC pad, or T for AT pad)
and
y
represents the appropriate Analog Quad number. Example: If the AT pad in Analog Quad 5 is
configured as a digital input, it will come out on the DATOUT5 pin of the Analog Block macro.
