Raster Control 2 for video port. This pin provides an HS pulse
of programmable length or receives an HS pulse.
Real Time Control input. If the LLC clock is provided by an
SAA7111 or SAA7151B, RTCI should be connected to the
RTCO pin of the respective decoder to improve the signal
quality.

Crystal oscillator input (from crystal). If the oscillator is not
used, this pin should be connected to ground.
Crystal oscillator output (to crystal).
digital supply voltage for the internal oscillator; note 1
not connected
Line-Locked Clock. This is the 27 MHz master clock for the
encoder. The I/O direction is set by the CDIR pin.
digital supply voltage 7
Clock direction. If CDIR input is HIGH, the circuit receives a
clock signal, otherwise if CDIR is LOW, LLC is generated by
the internal crystal oscillator.
digital ground 7
Lower reference voltage 1 input for DACs; connect to analog
ground.
Upper reference voltage 1 input for DACs; connect via 100 nF
capacitor to analog ground.
Analog supply voltage 1 for DACs.
Analog output of the BLUE component.
reserved
Analog supply voltage 2 for DACs.
Analog output of GREEN component.

Analog supply voltage 3 for DACs.
Analog output of RED component.
