DESCRIPTION
Analog inputs. Red channels. AC-couple through 0.1µF.
Analog inputs. Green channels. AC-couple through 0.1µF.
Analog inputs. Blue channels. AC-couple through 0.1µF.
Analog inputs. Reference voltage for ADCs. Tie to 1.8V reference voltage (V_A1.8 is acceptable if low noise). Decouple with
0.1µF capacitor to GND_A.
Analog inputs. Sync on Green. Connect to corresponding Green channel video source through a 0.01µF capacitor in series
with a 500Ω resistor.
Digital high impedance 3.3V inputs with 240mV hysteresis. Connect to corresponding channel's HSYNC source. For 5V
signals divide input with a 1k/1.9k divider. Place the divider as close as possible to the device pin. Place a 50pF capacitor
in parallel with the 1k resistor to reduce the filtering effect of the divider.

Digital 3.3V input. When this input is high and external COAST is selected, the PLL will coast, ignoring all transitions on
the active channel’s HSYNC/SOG.
