I/O
−
Voltage reference for PLL analog supply 1.8 V.
O PLL external filter return
O PLL negative input. Connected to PLL_FLT_RTN via an RC network
I PLL positive input. Connected to PLL_FLT_RTN via an RC network
−
Analog ground
−
Analog ground
−
Voltage reference for PLL digital supply 1.8 V.
−
Analog ground for PLL.
−
3.3-V analog power supply for PLL
−
Band gap voltage reference.
I System reset input, active low.
I Headphone in/out selector.
I Power down, active low. PDN powers down all logic and stops all clocks whenever a logic low is applied.
I Soft mute of outputs, active low (Muted signal = a logic low, normal operation = a logic high)
