Dear sir,

Part No : EL1883ISZ (Manufacturer : Intersil)

I want to calculate / choose the RSET value for below timings(VGA timings for 640 pixes X 480 pixes ,refresh rate = 60Hz)
HSYNC :

1.Horizontal Line frequency = 31.469 KHz
2.Horizontal SYNC polarity = Negative
3.Active video = 24.422 usec

VSYNC:

1.Total time for each frame = 16.683 msec
                                              =60Hz(refresh rate)
2.Vertical SYNC polarity = Negative
3.Vertical Lines =480
SYNC pulse length = 0.064msec
