An offset on the PLL loop filter will cause an offset
in the two 1

from drifting-off frequency.

V 12V
Doubled bonded (two bond wires and two pads for
one package pin) :
- One pad is connected to all of the 12V ESD and
video guard rings.
- The second pad is connected to power up the
video block.
V GND
Doubled bonded :
- One pad is connected to power-up all of the video
mux and I/O.
- The second pad is only as a low noise GND for
the video input.
VDD 5V, GND 5V
Connected to XTL oscillator and the bulk of the
CMOS logic and 5V ESD.
