just

(1) Apply input signal 1 (f0 = 10kHz, 0.5Vp-p) to pin 39.

(2) Set the data of sub-address (03) is (40).

â â (40) â

(3) Measure the output signal amplitude at pin 21. (VCNCENT)

(4) Measure the output signal amplitude at pin 21 when the data of sub-address

(03) is set (7F) (VCNMAX)

(5) Measure the output signal amplitude at pin 21 when the data of sub-address

(03) is set (00) (VCNMIN)

GCNMAX = 20âog (VCNMAX / VCNCENT)

GCNMIN = 20âog (VCNMIN / VCNMAX)

Measure the blanking pulse voltage at pin 21.
