Description
Analog Power (1.8V) for A & B Channels. Must be bypassed with 0.1uF capacitor to the analog system
ground plane.
No Connection. Leave this pin open for normal operation.
Analog Ground (1.8V Return) for C channel. Must be directly connected to the analog system ground plane
on board.
Analog Power (1.8V) for C Channel. Must be bypassed with 0.1uF capacitor to the analog system ground
plane.
Analog Front End Test O/P. Leave this Pin open. Used for factory testing purpose only.
Analog Power (3.3V) for ADC. Must be bypassed with 0.1uF capacitor to the analog system ground plane.
Analog Ground. Must be directly connected to the analog system ground plane on board.
Analog Ground. Must be directly connected to the analog system ground plane on board.
Positive analog sync input for channel 1.
The input has to be AC coupled using a series 20 Ohm resistor and 0.1uF Capacitor network.
