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