The use of INTREQ/GPCL/VBLK, AVID, HSYNC, and VSYNC/PALI is optional.
When OSC_IN is connected through S1, remove the capacitors for the crystal.
PDN needs to be high, if device has to be always operational.
RESETB is operational only when PDN is high. This allows an active-low reset to the device.
100-kΩ resistor (R) in parallel with the crystal is recommended for most crystal types.
Anti-aliasing filter (AAF) highly recommended for best video quality.
System level ESD protection is not included in this application circuit, but it is highly recommended on the analog
video inputs.
An external 10-kΩ pulldown resistor is required when the INTREQ/GPCL/VBLK output (pin 27) is disabled (bit 5 of I
2
C
register 03h is set to 0).
An external 10-kΩ pullup resistor is required when the INTREQ/GPCL/VBLK output (pin 27) is enabled and
configured as an active-low interrupt (bit 5 of I
2
C register 03h is set to 1, bit 1 of I
2
C register 0Fh is set to 0, and bit 0
of I
2
C register 1Eh is set to 0).
