1.1.6. Non-Altera Device Transmitter to Stratix V PCML Receiver

DC-coupling between a non-Altera transmitter to a Stratix V PCML receiver is supported if all the following conditions are satisfied:

  • Trace length is less than or equal to 3 inches
  • Channel loss is less than 4 dB
  • Data rate is less than or equal to 10.3125 Gbps
  • Application does not use backplanes or optical connectors

You must maintain the non-Altera transmitter common mode voltage within +/- 100 mV of the Altera Stratix V receiver.

Note: You can measure the transmitter common mode voltage at the transmitter pin using a DC multi-meter or a high impedance oscilloscope probe.

Contact Intel Premier Support, if your application requires the following conditions. In this case the minimum VID required for the Stratix V receiver will be higher than what is specified in the datasheet.

  • Trace length is more than 3 Gbps
  • Channel loss is more than 4 dB
  • Data rate is higher than 10.3125 Gbps
  • Application uses backplanes or optical connectors
