Pin Functions
No. Pin Name I/O Pin Function
1 VRA_PLL
−
Voltage reference for PLL analog supply 1.8 V.
2 PLL_FLT_RET O PLL external filter return
3 PLL_FLTM O PLL negative input. Connected to PLL_FLT_RTN via an RC network
4 PLL_FLTP I PLL positive input. Connected to PLL_FLT_RTN via an RC network
5 AVSS
−
Analog ground
6 AVSS
−
Analog ground
7 VRD_PLL
−
Voltage reference for PLL digital supply 1.8 V.
8 AVSS_PLL
−
Analog ground for PLL.
9 AVDD_PLL
−
3.3-V analog power supply for PLL
10 VBGAP
−
Band gap voltage reference.
11 RESET I System reset input, active low.
12 HP_SEL I Headphone in/out selector.
13 PDN I Power down, active low. PDN powers down all logic and stops all clocks whenever a logic low is applied.
14 MUTE I Soft mute of outputs, active low (Muted signal = a logic low, normal operation = a logic high)
15 DVDD
−
Digital power 3.3-V supply for digital core and most of I/O buffers
16 DVSS
−
Digital ground for digital core and most of I/O buffers
17 VR_DPLL
−
Voltage reference for digital PLL supply 1.8 V.
18 OSC_CAP O Oscillator capacitor
19 XTL_OUT O XTL_OUT and XTL_IN are the only LVCMOS terminals on the device.
20 XTL_IN I XTL_OUT and XTL_IN are the only LVCMOS terminals on the device.
