Multiple jumpers are provided on the EVM for configuration of TDP1204 and also for probe points.
The following is a list of 4-level jumpers which are used to configure the TDP1204: JMP4, JMP5, JMP6, JMP7, JMP8, JMP9, and JMP13. The jumper position to select between the different levels is detailed in Table 2-1.
Jumper Position | 4-level State |
---|---|
Short 4 to 6 | 0 |
Short 3 to 4 | R |
Open | F |
Short 2 to 4 | 1 |
Jumper | Default Position | Description |
---|---|---|
JMP4 | Short 4 to 6 | MODE.
Default is pin-strap mode. If I2C mode is desired, leave this jumper open or no-connect. Refer to data sheet for more details. |
JMP5 | Short 2 to 4 | CTLEMAP_SEL. Refer to data sheet for details on different CTLEMAP options. |
JMP6 | Open | EQ1. In pin-strap mode, this jumper along with JMP8 (EQ0) will select the EQ value for the receiver. The EQ may need to be tuned based on quality of HDMI cable used. Refer to data sheet for details on EQ options. |
JMP7 | Open | TXPRE. Refer to data sheet for details. |
JMP8 | Short 4 to 6 | EQ0/ADDR. In pin-strap mode, this jumper along with JMP6 (EQ1) will select the EQ value for the receiver. The EQ may need to be tuned based on quality of HDMI cable used. Refer to data sheet for details. |
JMP9 | Open | TXSWG. Refer to data sheet for details. |
JMP13 | Short 4 to 6 | LINEAR_EN. Refer to data sheet for details. |
JMP15 | Short 4 to 6 | SCL and CFG0. Short 1 to 3: I2C clock from TUSB3410 (U7). Short 3 to 5: I2C clock from Aardvark connector (J5). Short 2 to 4: CFG0 pulled up to VIO (3.3 V). Refer to data sheet for details on CFG0. Short 4 to 6: CFG0 pull-down to GND. Refer to data sheet for details on CFG0. |
JMP16 | Short 4 to 6 | SDA and CFG1. Short 1 to 3: I2C data from TUSB3410 (U7). Short 3 to 5: I2C data from Aardvark connector (J5). Short 2 to 4: CFG1 pulled up to VIO (3.3 V). Refer to data sheet for details on CFG1. Short 4 to 6: CFG1 pull-down to GND. Refer to data sheet for details on CFG1. |
J25 | Short 2 to 3 | HPDOUT_SEL. Short 1 to 2: HPD_OUT is open drain. Short 2 to 3: HPD_OUT is push-pull. |
J27 | Short 2 to 3 | AC_EN Short 1 to 2: OUT_D[2:0] and OUT_CLK is AC-coupled. Make sure R171, R172, R173, R174, R175, R176, R177, and R178 are populated with 100 nF capacitor or make sure AC capacitor is external to EVM board. Short 2 to 3: OUT_D[2:0] and OUT_CLK is DC-coupled. Make sure R171, R172, R173, R174, R175, R176, R177, and R178 are populated with 0-Ω resistor. |
J31 | Short 2 to 3 | DDC Level Shifter
enable/disable Short 1 to 2: Discrete DDC level shifter (U23) disabled. Short 2 to 3: Discrete DDC level shifter (U23) enabled. |
J32 | Short 1 to 2 | VIO Voltage. Short 1 to 2: VIO connected to board 3.3 V. OPEN: VIO is from an external supply. |
