Input and Output Connections
J8
20 position wall
header
Connect to FPD-Link output.
J1
Automotive HSD
Connector
Connect to FPD-Link II input (default).
J9 and J10 SMA Connector
Connect to FPD-Link II input.
(When using these connectors, R3 and R4 should be placed with 0Ω resistors, the traces
from R3 and R4 to the J1 should be cut).
J2 USB Connector
Connect to FPD-Link II input.
(When using this connector, P1 should be removed, and R24 and R25 should be placed
with 0Ω resistors)
JP12 and JP13
Power Wire in USB
cable through J2
Connect to VSS is recommended.
Control Connections
JP4 TESTEN NSC test mode. Always connect it to “L” or leave it unconnected.
JP5 LF_MODE Connect to “L” or “H” for the PCLK frequency select. See datasheet for detail information.
JP6 OSSEL Connect to “L” or “H” for the Output State select. See datasheet for detail information.
JP7 MAPSEL
Connect it to “L” or “H” for the FPD Link mapping select. See datasheet for detail
information.
JP8 VODSEL
Connect it to “L” or “H” for the FPD-Link VOD level select. See datasheet for detail
information.
JP9 OEN Connect it to “L” or “H” for the Output Enable select. See datasheet for detail information.
JP10 BISTEN Connect it to “H” for the BIST enable mode. See datasheet for detail information.
- PDB
Connect it to “L” for the power down mode. Connect it to “H” for the enable mode.
See datasheet for detail information.
- SSC[2:0] Connect them to “L” or “H” for the SSCG selection.
- CONFIG Configuration select. See datasheet for detail information.
JP24 and VR3 ID[x]
Connect JP24 to VSS to have the default device PHY address (h’DC).
Connect JP24 to VR3; then adjust VR3 value to select desired device PHY address. See
datasheet for detail information.
J3 and JP23 I2C Interface Connect JP23 if the I2C power is not supplied on J6. Otherwise, leave it unconnected.
Others
LED1 PASS PASS output. “ON” when PASS is “H”
LED2 LOCK LOCK output. “ON” when LOCK is “H”
JP11, JP25, JP26 Other options Do not connect
