Clock Termination Return
B20
SAMPADJ
Sampling Point Adjustment Input. Allows the user to adjust the sampling event by applying a
voltage between 0 to 2.5V to this input.
B19
DELGATE1
Timing Delay Adjustment. Coarse (MSB) adjustment for the timing between T/H amplifier and
quantizer.
C19
DELGATE0
Timing Delay Adjustment. Coarse (LSB) adjustment for the timing between T/H amplifier and
quantizer.
Y20
REFIN
Reference Voltage Input. For applications requiring improved gain performance and reference-
voltage adjustability, allows the user to utilize the REFIN input by applying a more accurate and
adjustable reference source. This input accepts an input-voltage range of 2.5V ±10%.
Y19
REFOUT
Internal Reference Output. Connect to REFIN, if using the internal 2.5V bandgap reference.
V18, W18, Y18
GNDR
Bandgap Reference Ground. Ground connection for the internal bandgap reference and its
related circuitry.
M20
INP
True/Positive Analog Input Terminal. For single-ended signals, apply signal to INP and reverse-
terminate INN to GNDI with a 50
resistor.

W20
VOSADJ
Analog Voltage Input to Adjust the Converter Offset. This input accepts an input-voltage range of
0 to 2.5V allowing the offset to be adjusted at roughly ±10 LSB.
M4
DORP
True/Positive LVDS Data-Overrange Output Bit. This output flags over- and under-range
conditions of the data converter.
M3
DORN
Complementary/Negative LVDS Data-Overrange Output Bit. This output flags over- and under-
range conditions on the data converter.
M2
DCOP
True/Positive LVDS Data Clock Output. Synchronize user-supplied data-capture board or data-
acquisition system to this clock.
M1
DCON
Complementary/Negative LVDS Data Clock Output. Synchronize user-supplied data-capture
board or data-acquisition system to this clock.
