Specifications

Recommended Operating Conditions

  MIN TYP MAX UNIT
Supply voltage SYS_DCIN +8 +12 +17 V
Output current
+1V8 (pin 35)
Low-speed
expansion socket
0   200 mA

Power Consumption

The specifications below refer to the total power consumption of the mezzanine card and the carrier board combined. It is important to note that the use of the mezzanine will affect the power consumption of the SoC on the carrier board. This is due to the peripherals and IP that must be enabled on the SoC to interface with the Ethernet PHYs. Also note that the total power consumption is dependent on the ambient temperature and channel utilization.

Ultra96-v1

  SYS_DCIN UTILIZATION MIN TYP MAX UNIT
Current draw 16 VDC 100%   510   mA
12 VDC 100%   645   mA
8 VDC 100%   935   mA
  • Tests performed at ambient temperature of 25 degrees C
  • Tests performed using IP in the FPGA to generate the Ethernet packets

Ultra96-v2

  SYS_DCIN UTILIZATION MIN TYP MAX UNIT
Current draw 16 VDC 100%   550   mA
12 VDC 100%   710   mA
8 VDC 100%   1050   mA
  • Tests performed at ambient temperature of 25 degrees C
  • Tests performed using IP in the FPGA to generate the Ethernet packets

Reset Timing

When hardware resetting the PHYs, we recommend using this timing:

  1. Hold the RESET_N signal LOW for 10ms
  2. Release the RESET_N signal (HIGH) and wait for 5ms

MDIO Timing

  • The maximum MDC frequency supported by the DP83867 PHY is 25MHz.
