MEASUREMENT METHOD

(00) (00) (40) (20) (80) (80) (80)

Measure the input impedance of pin 37 and 39.

(1) TV Mode

: Change the voltage in picture period at pin 37.

External Mode : Change the voltage in picture period at pin 39.

â (7F) â

(2) Consider the change of R output as 100%. Measure the DC voltage at pin 19

when output level of pin 19 is 10% (Vdi1). Measure the DC voltage at pin 41

when output level of pin 19 is 90% (Vdi2).

Vdi41 = Vdi2âVdi1

(1) TV Mode

: Apply the input signal 1

(f0 = 10kHz, 0.5Vp-p)

External Mode : Apply the input signal 1

â (40) â

(f0 = 10kHz, 0.5Vp-p)

(2) Measure the sine wave signal amplitude at pin 19 (V9)

G-Y = 20âog (V9 / 0.5Vp-p)

Measure input frequency when the output level becomes â3dB.

â (7F) â

(1) Same as Note 33 (1)

(2) Measure the maximum output level at pin 19.
