Pin # I/O Description
208 AP Analog Power (1.8V) for ABC & SYNC Channel. Must be bypassed with 0.1 uF capacitor to the
analog system ground plane.
209 AG Analog Ground (1.8V Return) for ABC & SYNC channel. Must be directly connected to the
analog system ground plane.
210 AP Analog Power (3.3V) for ADC. Must be bypassed with 0.1uF capacitor to the analog
system ground plane.
211 AI Sound Intermediate frequency input 2.
212 AG Analog ground. Must be directly connected to the analog system ground plane on board.
213 AG Analog ground. Routed through 56E to the analog system ground plane on board.
214 AG Analog ground. Must be directly connected to the analog system ground plane on board.
215 AI Sound Intermediate frequency input 1.
216 AP Analog Power (3.3V) for ADC. Must be bypassed with 0.1uF capacitor to the analog
system ground plane.
217 AI Positive analog input for channel 1. The input has to be AC coupled using a series 20 resistor
and 0.1uF Capacitor network.
218 AP Analog Power (3.3V) for ADC. Must be bypassed with 0.1uF capacitor to the analog
system ground plane.
219 AI Positive analog input 'A' for channel 1. The input has to be AC coupled using a series 20 resistor
and 0.1uF Capacitor network.
220 AG Analog ground. Must be directly connected to the analog system ground plane on board.
