SDA 9380 - B21
Warnings/Notes:
1) A change of INCR causes changes of the generated clock frequency more than the
specified 4.5%.
Switching from PLL mode to Generator mode (GENMOD) with constant INCR values does not
result in exceeding the specified frequency deviation range.
2) If pin SSD has H-level the output signal HD starts immediately after power on. In this case the
starting horizontal frequency is 31.25kHz (if FH1_2 = High). Starting with other frequencies requires
L-level at SSD so that INCR can be changed before enabling HD with HDE=1.
3) When SSD = High and FH1_2 = Low the horizontal frequency is fixed to 18.75 kHz (INCR = 20)
and cannot be changed via I²C bus. Other H-frequencies in the range of 15.6 kHz to 19 kHz are pos-
sible when SSD = Low.
4) The timing of the built-in soft start circuit (starting frequency, period, ending frequency) depends
on INCR. The starting frequency of the output HD is approx. 1.71* FH, the frequency stops at FH
defined by INCR (see table on previous page) The total soft start takes about 2.66*10³/FH. If the fre-
quency of the HSYNC input signal is outside the lock range of the PLL (+/- 4.5%), that means the
PLL cannot lock, the timing of the soft start may change max. +/- 4.5% due to the unlocked PLL.
