I
Analog video inputs. Up to six composite inputs, two component inputs, two S-video inputs or a combination
thereof. The inputs must be ac-coupled. The recommended coupling is 0.1
μ
F to 1
μ
F.
If inputs are not used, they may be tied to AFE_GND through a 0.1-
μ
F capacitor.
PCLK
27
O
Line-locked pixel clock output. The frequency corresponds to the video standard (see Table 2
–
1).
PREF
26
O
Line-locked clock phase reference signal output. This signal qualifies clock edges when SCLK clocks data
that is changing at the pixel clock rate. It may also be used as a stand-alone pixel clock.
SCLK
25
O
Line-locked system clock output with twice the frequency of the pixel clock (PCLK) (see Table 2
–
1).

O
10-bit digital chrominance outputs. These terminals may also be configured to output the data from the
channel 2 A/D converter. For the 8-bit mode, the two LSBs are ignored.
Unused outputs can be left unconnected.

O
10-bit digital luminance outputs, or 10-bit multiplexed luminance and chrominance outputs. These terminals
may also be configured to output the data from the channel 1 A/D converter. For the 8-bit mode, the two LSBs
are ignored.
Unused outputs can be left unconnected.
