I/O Description
AP Analog Power (1.8V) for ABC & SYNC Channel. Must be bypassed with 0.1 uF capacitor to the
analog system ground plane.
AG Analog Ground (1.8V Return) for ABC & SYNC channel. Must be directly connected to the
analog system ground plane.
AP Analog Power (3.3V) for ADC. Must be bypassed with 0.1uF capacitor to the analog
system ground plane.
AI Sound Intermediate frequency input 2.
AG Analog ground. Must be directly connected to the analog system ground plane on board.
AG Analog ground. Routed through 56E to the analog system ground plane on board.
AG Analog ground. Must be directly connected to the analog system ground plane on board.
AI Sound Intermediate frequency input 1.
AP Analog Power (3.3V) for ADC. Must be bypassed with 0.1uF capacitor to the analog
system ground plane.
AI Positive analog input for channel 1. The input has to be AC coupled using a series 20 resistor
and 0.1uF Capacitor network.
AP Analog Power (3.3V) for ADC. Must be bypassed with 0.1uF capacitor to the analog
system ground plane.
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.
AG Analog ground. Must be directly connected to the analog system ground plane on board.
