Measuring Procedure
Connect a DC ammeter to the VCC pin and measure. The
ammeter is shorted for use in subsequent measurements.
Input a 1.0VP-P, 100kHz sine wave to SG, and obtain GV
from the following formula given TP1 voltage as V1
and TP3 voltage as V2.
GV=20LOG (V2/V1) dB
For the above GV measurement, given TP3 voltage for
10MHz as V3, FC is obtained from the following
formula.
FC=20LOG (V3/V2) dB
Input a 1.0VP-P staircase wave to SG, and measure
differential gain at TP3.
APL=10~90%
Proceed as for DG, and measure differential phase.
Measure the DC voltage difference of each switch
status at TP2.
Assume VC1=2.1V, VC2=0.7V.
Input a 2.0VP-P, 4.43MHz sine wave to SG, and given
TP1 voltage as V4 and TP3 voltage as V5, CT is
obtained from the following formula.
CT = 20LOG (V5/V4) dB
Impress an optional DC voltage on TP6 and TP7.
Gradually raise from VC1=0V. TP4 voltage when TP7
voltage is output on TP2 is VIH1. Gradually lower from
VC1=VCC. TP4 voltage when TP6 voltage is output on
TP2 is VIL1.
Impress an optional DC voltage on TP6 and TP8.
Gradually raise from VC1=0V. TP5 voltage when TP8
voltage is output on TP2 is VIH2. Gradually lower from
VC1=VCC. TP5 voltage when TP6 voltage is output on
TP2 is VIL2.
