Digital Circuitry Input Reference
Pin 53
- Main Clock Input
LLC2(53)
This is the input for the line-locked clock signal. The fre-
quency can be 27, 32, or 40.5 MHz.
Pin 54...61
- Picture Bus Luma
Y0...Y7
The Picture Bus Luma lines carry the digital luminance
data.
Pin 62
- Line-Locked Clock Input
LLC1
This is the reference clock for the single frequency input
sync signals required in a FIFO application. The frequency
can be 13.5, 16, or 20.25 MHz.
Pin 63
- Sync Signal Input
HS
This pin gets the horizontal sync information. Either single
or double horizontal frequency or VGA horizontal sync sig-
nal.
Pin 64
- Sync Signal Input
VS
This pin gets the vertical sync informatoion. Either single
or double vertical frequency or VGA vertical sync signal.
Pin 65, 66
- Crystal Output / Input
XTAL2 / XTAL1
These pins are connectecd to an 5-MHz crystal oscillator.
The security unit for the HOUT signal uses this clock sig-
nal as reference.
Pin 67
- Data Input/Output
SDA
Via this pin the - bus data are written to or read from
the DDP 3310B.
Pin 68
- Clock Input
SCL
Via this pin, the clock signal for the -bus will be sup-
plied. The signal can be pulled down by an internal tran-
sistor.
* Application Note :
All ground pins should be connected separeately with
short and low-resistive lines to a central power supply
ground. Accordingly, all supply pins should be connected
separately with short and low-resistive lines to the power
supply. Decoupling capacitors from VSUPP to GNDP,
VSUPD to GNDD, and VSUPO to GNDO are recom-
mended to be placed as closely as possible to the pins.
