2.2 Header and Jumper Information

Table 2-1 TAS5802 Circuit Jumpers
Designator Name Positions Description
J2 PVDD_EXT

IN: Default, external PVDD supplies PVDD for device 1

OUT: PVDD disconnected for device 1

 Drives the analog power supply for the first TAS5802. If PVDD current draw wants to be measured can use this jumper for a current probe
J5 PVDD1

IN: Default, external PVDD supplies PVDD for device 1

OUT: PVDD disconnected for device 1

 Drives the analog power supply for the first TAS5802. If PVDD current draw wants to be measured can use this jumper for a current probe
J7 DVDD1

IN: Default, IOVDD supplies DVDD for device 1

OUT: DVDD disconnected for device 1

 Drives the digital power supply for the first TAS5802. If DVDD current draw wants to be measured need to externally drive DVDD to pin 2
J12 PVDD2

IN: Default, external PVDD supplies PVDD for device 2

OUT: PVDD disconnected for device 2

 Drives the analog power supply for the second TAS5802. If PVDD current draw wants to be measured can use this jumper for a current probe
J13 DVDD2

IN: Default, IOVDD supplies DVDD for device 2

OUT: DVDD disconnected for device 2

 Drives the digital power supply for the second TAS5802. If DVDD current draw wants to be measured need to externally drive DVDD to pin 2
J16 SDIN2_SEL

1-2: SDIN from I2S MUX

2-3: Default, SDIN from SDOUT of first TAS5802

 Selects the serial data input for the second device.

Table 2-4 XMOS Circuit Jumpers
Designator Name Position Description
J17 SCL

1-2: Default, PPC3 drives XMOS I2C bus to the TAS5802

OUT: Use Pin 1 and 3 to drive SCL externally to the TAS5802 on the EVM

 The SCL Jumper offers a few options to provide or receive I2C signals. Default configuration connects the XMOS I2C bus to the TAS5802 to configure the device with PPC3. Disconnecting the jumper allows for the XMOS I2C bus to be connected to an external TAS5802 system board to configure that device with PPC3 using pins 2 and 3. Alternatively can use an external I2C bus to drive the TAS5802 on the EVM using pins 1 and 3.
J18 SDA

1-2: Default, PPC3 drives XMOS I2C bus to TAS5802

OUT: Use Pin 1 and 3 to drive SDA externally to the TAS5802 on the EVM

 The SDA Jumper offers a few options to provide or receive I2C signals. Default configuration connects the XMOS I2C bus to the TAS5802 to configure the device with PPC3. Disconnecting the jumper allows for the XMOS I2C bus to be connected to an external TAS5802 system board to configure that device with PPC3 using pins 2 and 3. Alternatively can use an external I2C bus to drive the TAS5802 on the EVM using pins 1 and 3.

Designator Name Positions Description
J21 IOVDD

1-2: 1.8V IOVDD

2-3: Default, 3.3V IOVDD

 Sets the IOVDD voltage for the digital interfaces
J22 SCLK

1-2: Default, Bypass mode that sends SPDIF and XMOS I2S input to the TAS5802

2-3: Connect external PSIA connector to Pin 2-3 to drive input to TAS5802

 Sets the SCLK input to be driven internally using USB/Optical input or driven externally with a PSIA connector
J23 LRCLK

1-2: Default, Bypass mode that sends SPDIF and XMOS I2S input to the TAS5802

2-3: Connect external PSIA connector to Pin 2-3 to drive input to TAS5802

 Sets the LRCLK input to be driven internally using USB/Optical input or driven externally with a PSIA connector
J24 SDIN

1-2: Default, Bypass mode that sends SPDIF and XMOS I2S input to the TAS5802

2-3: Connect external PSIA connector to Pin 2-3 to drive input to TAS5802

 Sets the SDIN input to be driven internally using USB or optical input or driven externally with a PSIA connector
J26 GPIO1 SEL

1-2: Default, sends the SDOUT data to the XMOS

2-3: Sends SDOUT Data to SPIDIF Optical Output

 If the device is not using the Class-H feature, then this jumper can be using to sent the output I2S/TDM data to an external source of either the XMOS and USB or the optical output
