TEST CONDITION (V_CC = 9V, Ta = 25±3°C)
MEASUREMENT METHOD
(1) Same as Note 3 (1)
(2) Set the data of sub-address (08) to (00). Decrease the IF input level. Measure
the IF input level, when the voltage of pin 3 become 4.5V. (V_RFMIN)
(3) Set the data of sub-address (08) to (3F). Measure the IF input level, when the
voltage of pin 3 become 4.5V. (V_RFMAX)
∆V_RFAGC = V_RFMIN−V_RFMAX
(1) No IF input
(2) Apply 3.0V to pin 5.
(3) Measure the voltage at pin 44. (V_4CENT)
(1) Apply the signal (f = 44.75MHz, 30% AM Video, 31.6mV_rms) to IF input.
(2) Measure the output signal level at pin 44. (V_4MAX)
(3) Apply the signal (f = 46.75MHz, 30% AM Video, 31.6mV_rms) to IF input.
(4) Measure the output signal level at pin 4. (V_4MIN)
(1) Same as Note 3 (1)
(2) Measure the voltage change at pin 44 when input frequency is changed. (∆_f /
∆_V)
Measure the output impedance of pin 44.
