SM320C6678-HIREL: SGMII PHY

Part Number: SM320C6678-HIREL
Other Parts Discussed in Thread: DP83869

SM320C6678-HIREL has SGMII, and operates under -55C, I need to have a SGMII PHY operates under -55C, could you help me to find one? or are there SGMII to RGMII converter and RGMII PHY that operate under -55C? 

Here are the two approaches, operating temperature under -55C

1. SM320C6678-HIREL -> SGMII PHY -> RJ45

2. SM320C6678-HIREL -> SGMII to RGMII converter -> RGMII PHY -> RJ45
