... M52390FP Usage Precautions (1) Typical values for input signals (2) Setting the Free Run frequency This IC generates the fsc by means of the VCXO circuit. Consequently, the VCXO oscillation frequency must always be set to fsc before the IC is used, by following the procedure outlined below. 1. Connect [9] (VIDEO IN) to GND, and set the Free Run mode. ...

... M52390FP (3) Setting the color difference LPF The frequency characteristic of the color difference LPF built into this IC can be set as shown in Fig. 1, using the [20] (fc CONT.) external resistor. When doing this, the group delay characteristic also changes, as shown in Fig. 2. (4) Setting Y DL The group delay characteristic of the color signal of the RGB encoder output changes in response to the [20] (fc CONT) external resistor should be set in such a way that the group delay characteristic is the amount of group delay obtained from the group delay characteristic of Fig ...

(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 ...
