(Fig. 4–11)
These are analog component inputs without fastblank
control. A RGB or YC
r
C
b
signal is converted using the
component AD converter. The input signals must be
AC-coupled.

C Bus Data SDA (Fig. 4–12)
This pin connects to the I
2
C bus data line.
Pin 15 – Reset Input RESQ (Fig. 4–3)
A low level on this pin resets the VPC 32xx.
Pin 16 – Test Input TEST (Fig. 4–3)
This pin enables factory test modes. For normal opera-
tion, it must be connected to ground.
Pin 17 – VGAV-Input (Fig. 4–3)
This pin is connected to the vertical sync signal of a VGA
signal.
Pin 18 – YC Output Enable Input YCOEQ (Fig. 4–3)
A low level on this pin enables the luma and chroma
outputs.

This pin is connected to the IE pin of the external field
memory.
Pin 20 – FIFO Write Enable FFWE (Fig. 4–4)
This pin is connected to the WE pin of the external field
memory.
Pin 21 – FIFO Reset Write/Read FFRSTW (Fig. 4–4)
This pin is connected to the RSTW pin of the external
field memory.
Pin 22 – FIFO Read Enable FFRE (Fig. 4–4)
This pin is connected to the RE pin of the external field
memory.
Pin 23 – FIFO Output Enable FFOE (Fig. 4–4)
This pin is connected to the OE pin of the external field
memory.
Pin 24 – Main Clock Output CLK20 (Fig. 4–4)
This is the 20.25 MHz main clock output.
