Setup instruction for evaluation PCB
(1) Horizontal blanking pulse adjustment
The timing and pulse width of the horizontal blanking pulse should be as shown in the following figure by
adjusting the variable resistor of the single shot multi vibrator.
pin 7 (H OUT)
8µs
Horizontal blanking
pulse
12µs
The variable resistor at pin 15 of TTL IC 'M74LS221P' is used to fix the timing at 8µs and that at pin 7 is used to
fix the pulse width at 12µs.
(2) VIF VCO adjustment
Before measurement of M61203CFP, VIF VCO must be adjusted by the following procedure.
(1) Input I2C bus data of VIF Freq (01H D6), according as IF frequency.
(45.75MHz : 0, 58.75MHz : 1)
(2) Input I2C bus data of VIF Defeat ON (07H D7 = 1).
(3) Set the DC voltage at pin 60 (AFT OUT) to 2.5V by adjusting I2C bus data of VCO control (01H D0-D5).
(4) Input I2C bus data of VIF Defeat OFF (07H D7 = 0).

(3) H VCO adjustment
Before measurement of M61203CFP, H VCO must be adjusted by the following procedure.
(a) Set the frequency at pin 7 (H OUT) to about 15.734kHz by adjusting I2C bus data of H VCO control
(10H D3-D5).
