Connect a DC ammeter to the V
CC
pin and measure. V
CC
is 5V and
the ammeter is shorted for use in subsequent measurements.
Input a 2.0V
P-P
, 100kHz sine wave to SG, and obtain G
V
from the
following formula given TP12 voltage as V1 and TP14 voltage as V2.
G
V
=20LOG (V2/V1) dB
For the above G
V
measurement, given TP14 voltage for 10MHz as
V3, F
C
is obtained from the following formula.
F
C
=20LOG (V3/V2) dB
Input a 2.0V
P-P
staircase wave to SG, and measure differential gain at TP14.
APL=10~90%
Proceed as for DG, and measure differential phase.
Input a 2.5V
P-P
, 1kHz sine wave to SG, connect a distortion meter to
TP14 and measure.
Measure the DC voltage difference of each switch status at TP13.
Assume VC1=2.1V, VC2=0.7V.
Input a 2.0V
P-P
, 4.43MHz sine wave to SG, and given TP12 voltage as V4
and TP14 voltage as V5, C
T
is obtained from the following formula.
