Critical Layout Note:
C8 negative terminal and C12 negative terminal connecting to PGND
should both be placed
very close to pin 6 of the US1000FV01 device.
The PGND-GND 50-mil tie connection should be clos e to the
C8/C12/Pin_6 junction.
Doing this will minimize the GND bounce in the DC-DC converter area.
VDDO_1 - Input supply which internally powers I2S TX, I2C Slave and SPI Master Interfaces.
VDDO_2 - Input supply which internally powers I2S RX, GPIOs and UART interfaces.
VDDO_3 - Input supply which internally powers the USB interface.
near US1000FV01 pin 43
Note:
I2S_TX_CLK1, I2S_TX_DATA, I2S_TX_LRCK1,
I2S_RX_CLK1, I2S_RX_DATA_1, I2S_RX_DATA_2,
I2S_RX_LRCK1 signals are connected
off-board.
I2S_TX to ISP Device for Digital Audio:
1. Pin 3 --> I2S_TX_CLK
2. Pin 1 --> I2S_TX_DATA_1
3. Pin 2 --> I2S_TX_LRCK
4-CH Echo Reference I2S:
1. Pin 22 --> I2S_RX_CLK
2. Pin 23 --> I2S_RX_DATA1
3. Pin 25 --> I2S_RX_DATA2
4. Pin 24 --> I2S_RX_LRCK
Note: Place C123, R98,R100 and R160 close to U1 pin
2-CH Echo Reference I2S:
1. Pin 22 --> I2S_RX_CLK
2. Pin 23 --> I2S_RX_DATA1
3. Pin 24 --> I2S_RX_LRCK

Note:
SPI Flash device used in this
design supports 3.3V. If 1.8V
signaling is required, make
sure to select a SPI flash
device that supports 1.8V
signal level.
Note:
S_SCL, S_SDA, WAKE_ON_VOICE and
CX_RESET signals intended to connect
to ISP Device.
