MITSUBISHI ICs (TV)

5. AGC Control Range: GR

GR = VIN MAX - VIN M IN

(dB)

7. Capture range: CL - U

1. Increase the frequency of SG9 until the VCO is out of locked-oscillation.

2. Decrease the frequency of SG9 and measure the frequency fU when the

VCO locks.

CL - U = fU - 58.75

(MHz)

8. Capture range: CL - L

1. Decrease the frequency of SG9 until the VCO is out of locked-oscillation.

2. Increase the frequency of SG9 and measure the frequency fL when the

VCO locks.

CL - L = 58.75 - fL

(MHz)

9. Capture range: CL - T

CL - T = CL - U + CL - L

(MHz)

6. RF AGC Operating Voltage: V3

Input SG8 into VIF IN and gradually reduce Vi and then measure the input

level when RF AGC output TP3 reaches 1/2 VCC, as shown below.
