OSD clock. Output clock to external microprocessor to
synchronize OSD data.
Video output. As programmed by Command Register
OFMT
00 Luminance component Y of S-video.
01 Red component of RGB.
1X V component of YUV
Video output. As programmed by Command Register

00 Composite video.
01 Green component of RGB.
1X Y component of YUV.
Video output. As programmed by Command Register
OFMT
00 Chrominance component of S-video.
01 Blue component of RGB.
1X U component of YUV.
Composite sync output. Digital composite sync for YUV
and RGB/SCART video outputs. High impedance (tri-state)
when powered down.
Horizontal sync output. Digital horizontal sync for YUV,
RGB/SCART, and progressive video outputs. High
impedance (tri-state) when powered down. Note:
multiplexed with R
Vertical sync output. Digital horizontal sync for YUV,
RGB/SCART, and progressive video outputs. High
impedance (tri-state) when powered down. Note:
multiplexed with R
Voltage reference input/output. If unconnected, except
for a 0.1µF capacitor to V
internal 1.235 Volt band-gap reference will be supplied to
the three D/A Converters. An external 1.235 volt reference
connected to C
reference.
Current Reference. A resistor between I
the current range of the D/A converters. Use 392Ω for a
37.5Ω load and 787Ω for a 75Ω load.
Bypass Capacitor. A 0.1µF capacitor must be connected
between C
outputs.
