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.
digital supply voltage 5 (3.3 V)
digital ground 5

digital ground 6 for oscillator
not connected
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 6 for oscillator (3.3 V)
Clock Reference signal. This is the clock qualifier for DIG-TV2 compatible signals.
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 (5 V)
Clock direction. If CDIR input is HIGH, the circuit receives a clock and optional
CREF signal, otherwise if CDIR is LOW, CREF and LLC are generated by the
internal crystal oscillator.
digital ground 7
Analog ground 1 for the DACs.
Analog test pin. Leave open-circuit for normal operation.
Analog supply voltage 1 for the RGB DACs (3.3 V).
Analog output of the BLUE component.
Analog input that can be switched to BLUE when SELI = HIGH.
Analog supply voltage 2 for RGB DACs (3.3 V).
Analog output of GREEN component.
Analog input that can be switched to GREEN when SELI = HIGH.
Analog supply voltage 3 for RGB DACs (3.3 V).
Analog output of RED component.
Analog input that can be switched to RED when SELI = HIGH.
Analog supply voltage 4 for DACs (3.3 V).
Analog supply voltage 5 for DACs (3.3 V).
Select analog input. Digital-to-analog converted RGB output when SELI = LOW;
RI, GI and BI output when SELI = HIGH.
not connected
Analog ground 2 for the DACs.
Analog supply voltage 6 for DACs (3.3 V).
Analog output of the chrominance signal.
Analog supply voltage 7 for the Y/C/CVBS DACs (3.3 V).
