VSAMP Delay Register
The VSAMP Delay register controls the internal delays added to the leading and the trailing edges of the
VSAMP timing signal. The width and position of the VSAMP pulse can be adjusted through the leading and
trailing edge delay settings. This is useful to match the sampling requirements of the incoming CCD/CIS
waveform.
* Power-on default value
VL[4:0] - Sets the amount of delay added to the leading edge of VSAMP.
VT[4:0] - Sets the amount of delay added to the trailing edge of VSAMP.
3.6
ADCLK Delay Register
The ADCLK Delay register controls the delay added to the ADCLK timing signal and Data Output.
* Power-on default value
A[4:0] - Sets the amount of internal delay added to the ADCLK signal.
DO[4:0] - Sets the amount of delay from internal ADCLK to valid data out.
3.7
Test Register
The TEST register is used for EXAR internal test requirements. Do not over write this register.
