3. Setup instruction for evaluation PCB
3.1 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.
pin50 (H OUT)
8µs
FBP
12µs
The variable resistor at pin15 of TTL IC 'M74LS221P' is used to fix the timing at 8s and that at pin7 is used to fix the
pulse width at 12µs.
3.2. H VCO adjustment
Before measurement of M65582MF, HVCO must be adjusted by the following procedure.
Set the frequency at pin50 (H OUT) to about 15.734kHz by adjusting I²C-Bus data of H VCO control (51H D0-D7).
