XTALI
44
Crystal oscillator input (from crystal). If the oscillator is not used, this pin should be connected
to ground.
XTALO
45
Crystal oscillator output (to crystal).
n.c.
46
not connected
CREF
47
Clock Reference signal. This is the clock qualier for DIG-TV2 compatible signals.
LLC
48
Line-Locked Clock. This is the 27 MHz master clock for the encoder. The I/O direction is set
by the CDIR pin.
VDDD7
49
digital supply voltage 7
CDIR
50
Clock direction. If the 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.
VSSD7
51
digital ground 7
VrefL1
52
