I/O
DESCRIPTION
Miscellaneous Signals
RSTOUTB
22
O
Reset output, active low
RSTINB
23
I
Reset input, active low
OEB
24
I/O
Output enable for Y and UV terminals. Output enable is also controllable via the host port. When this terminal
is a logic 1 forces Y and UV output terminals to high impedance states (active low).
GLCO
31
I/O
This serial output carries color PLL information. A slave device can decode the information to allow chroma
frequency control by the TVP5031. Data is transmitted at the SCLK rate. Additionally, this terminal, in
conjunction with PALI and FID, is used to determine the host port mode configuration during initial power
up.
GPCL
38
I/O
General-purpose control logic. This terminal has three functions:
1) General-purpose output. In this mode the state of GPCL is directly programmed via the host port.
2) Vertical blank output. In this mode the GPCL terminal is used to indicate the vertical blanking interval
of the output video. The beginning and end times of this signal are programmable via the host port.
3) Sync lock control input. In this mode when GPCL is high, the output clock frequencies and the sync timing
are forced to nominal values.

across the REFM and REFP terminals.
Sync Signals
AVID
28
I/O
Active video indicator. This signal is high during the horizontal active time of the video output on the Y and
UV terminals. AVID continues to toggle during vertical blanking intervals.
This terminal may be placed in a high-impedance state. During reset, AVID is an input, used to program the
behavior of Y[9:0], UV[9:0], HSYN, VSYN, AVID and FID immediately after the completion of reset. If AVID
is pulled up during reset, Y[9:0], UV[9:0], HSYN, VSYN, AVID, PALI and FID will be actively driving after
reset. If AVID is pulled down during reset, Y[9:0], UV[9:0], HSYN, VSYN, AVID, PALI and FID will remain
in high-impedance state after reset.
FID
33
I/O
Odd/even field indicator or vertical lock indicator. For odd/even indicator, a logic 1 indicates the odd field.
For vertical lock indicator, a logic 1 indicates the internal vertical PLL is in a locked state. Additionally, this
terminal in conjunction with GLCO and PALI is used to determine the host port configuration during initial
power up and reset.
