Circuit Function
3-4
3.1.2
References
In addition to the capability to configure the on-chip reference via jumpers, a
reference circuit has been included on the EVM. This uses a 1.2-V shunt refer-
ence diode (U2) as its primary source, and allows adjustment of the REFT and
REFB signals to the ADC using potentiometers R23 and R24, respectively.
The ranges of the external reference signals are: REFT, 0.60 V to 2.68 V,
REFB, 0 V to 1.79 V. See Chapter 4 for further details on the jumper settings
required to use this mode.
3.1.3
Power
Power is supplied to the EVM via banana jack sockets. A separate connection
is provided for a 3.3-V analog supply (J8 and J7) and 3.3-V digital supply (J10
and J11). J9 and J16 are only used when reprogramming the PLD device (not
required by the user).
3.1.4
Outputs
The data outputs from the ADC are buffered using SN74LVTH162244 before
going to header J12. Header J12 is a standard 40-pin device on a 100-mil grid,
and allows easy connection to a logic analyzer. The connector pinouts are
listed in Table 3
