Description
Digital Ground.
Analog Ground.
Pixel Clock Input for HD Only (74.25 MHz), PS Only (27 MHz), and SD Only (27 MHz).
Pixel Clock Input. Requires a 27 MHz reference clock for PS mode or a 74.25 MHz (74.1758 MHz)
reference clock in HDTV mode. This clock is only used in dual modes.
CVBS/Green/Y/Y Analog Output.
Luma/Red/V/Pr Analog Output.
In SD Only Mode: CVBS/Green/Y Analog Output; in HD Only Mode and Simultaneous HD/SD
Mode: Y/Green [HD] Analog Output.
In SD Only Mode: Luma/Blue/U Analog Output; in HD Only Mode and Simultaneous HD/SD
Mode: Pr/Red Analog Output.
In SD Only Mode: Chroma/Red/V Analog Output; in HD Only Mode and Simultaneous HD/SD
Mode: Pb/Blue [HD] Analog Output.
Video Horizontal Sync Control Signal for HD in Simultaneous SD/HD Mode and HD Only Mode.
Video Vertical Sync Control Signal for HD in Simultaneous SD/HD Mode and HD Only Mode.
Video Blanking Control Signal for HD in Simultaneous SD/HD Mode and HD Only Mode.
Video Blanking Control Signal for SD Only.
Video Vertical Sync Control Signal for SD Only.
SD or PS/HDTV Input Port for Y Data. Input port for interleaved progressive scan data. The LSB
is set up on Pin Y0. For 8-bit data input, LSB is set up on Pin Y2.
PS/HDTV Input Port 4:4:4 Input Mode. This port is used for the Cb[Blue/U] data. The LSB is set
up on Pin C0. For 8-bit data input, LSB is set up on Pin C2.
Compensation Pin for DACs. Connect 0.1 μF capacitor from COMP pin to V
Chroma/Blue/U/Pb Analog Output.
Video Horizontal Sync Control Signal for SD Only.
