data (even bits: D0+/-, D2+/-, …, D12+/-) being emitted
with the opposite clock edge during the second half of
the clock period. The odd data bits should be captured
with the falling edge of DRDY and the rising edge of
DRDY should be used to capture the even bits of the
data.
The data is available on the evaluation board at pins
A5/B5 (MSB +/-) through A11/B11 (LSB +/-) of the
FutureBus connector (schematic reference designator
FB). Please keep in mind that because the data is in
DDR format, pins A5/B5 will carry data bit D13+/-
during the first half of the clock period and these lines
will carry bit D12+/- during the second half of the clock
period. Similarly, pins A11/B11 will carry D1+/- during
the first half of the clock period and these pins will carry
D0+/- during the second half of the clock period. The
DRDY signal which is used to capture the data is also

in LVDS format and it is available at pins A4/D4
(DRDY+/-) on the FutureBus connector.
range bit (OVR) LVDS signal is available on pins
D22/D21 (OVR+/-) on the FutureBus connector.
Please see the Evaluation Board schematic in Section
5.0 and the ADC14V155 datasheet for further details.
4.5 Power requirements.
Power to the ADC14V155 evaluation board is supplied
through the green power connector labeled “+5V”
which is located along the bottom edge of the board.
Voltage and current requirements are:
• +5V capable of providing up to 500mA (ADC14V155
evaluation board only)
