PRODUCTION DATA.
The DOUT± outputs require 100-nF AC-coupling capacitors to the line. The power supply filter capacitors are placed near the power supply pins. A smaller capacitance capacitor should be located closer to the power supply pins.
The VODSEL pin is tied to VDDIO for the long cable application. The De-Emph pin may connect a resistor to ground. Refer to Table 2. The PDB and BISTEN pins are assumed controlling by a microprocessor. The PDB has to be LOW state until all power supply voltages reach the final voltage. The RFB pin is tied Low to latch data on the falling edge of the PCLK, High for the rising clock edge. The CNFIG[1:0] pins are set depending on operating modes and backward compatibility. The SCL, SDA and ID[x] pins are left open when these Serial Bus Control pins are unused. The RES[2:0] pins and DAP should be tied to ground.
