(6) The relationship between BFP and HHK

The pulse width of BFP and HHK can be set as shown in Fig. 4, using the [3] (HHK) external CR.

(7) Input pin drive

Input pins [9], [16], [17], and [18] use clamp input, so they should always be driven with a low impedance.

(8) Input/output relationship between SYNC and burst during the V cycle

(9) V DL and YS DL settings when the SUPERIMPOSE mode is being used

1) V DL is used to adjust the timing of the RGB encoder signal and the VIDEO IN signal.

2) YS DL is used to adjust the timing of the RGB encoder signal and the Ys IN signal.

3) When the timing is the same for C. SYNC IN, RGB IN, VIDEO IN and Ys IN, V DL and YS DL should be set

using the amount of delay shown below as a guide.

V DL = Y DL (item 4) + 10 (ns)

YS DL = Y DL – 10 (ns)
