PRODUCTION DATA
For a typical design application, use the parameters listed in Table 8-3.
| DESIGN PARAMETER | PIN(S) | VALUE |
|---|---|---|
| V(VDD) | VDDD, VDDDRV, VDDPLL | 1.8 V |
| AC-Coupling Capacitor for Synchronous Modes, Coaxial Connection | DOUT+ | 33nF – 100 nF (50 V / X7R / 0402) |
| DOUT– | 15nF – 47 nF (50 V / X7R / 0402) | |
| AC-Coupling Capacitor for Synchronous Modes, STP Connection | DOUT+, DOUT– | 33 – 100 nF (50 V / X7R / 0402) |
| AC-Coupling Capacitor for Non-Synchronous and DVP Backwards Compatible Modes, Coaxial Connection | DOUT+ | 100 nF (50 V / X7R / 0402) |
| DOUT– | 47 nF (50 V / X7R / 0402) | |
| AC-Coupling Capacitor for Non-Synchronous and DVP Backwards Compatible Modes, STP Connection | DOUT+, DOUT– | 100 nF (50 V / X7R / 0402) |
The SER/DES only supports AC-coupled interconnects through an integrated DC-balanced decoding scheme. External AC-coupling capacitors must be placed in series in the FPD-Link III signal path as shown in #SNLS4791057A and #SNLS4791056. For applications using single-ended 50-Ω coaxial cable, terminate the unused data pins (DOUT+, DOUT–) with an AC-coupling capacitor and a 50-Ω resistor.
