1. Kulekerera kwa wotchi ndi +/- 50 ppm
2. Mwachikhazikitso, ROCS12-(G)T ndi chipangizo chaduplex mumsewu wokonda kwambiri
3. Kudziwikiratu kwa crossover ndikoyambitsidwa.Chingwe chakunja cha crossover sichifunikira
4. 1000 BASE-T ntchito imafuna kuti makina ogwiritsira ntchito akhale ndi mawonekedwe a SGMII opanda mawotchi, ndi module PHY kukhazikitsidwa pa Application Note AN-2036.Ndi SERDES yomwe sigwirizana ndi SGMII, gawoli lidzagwira ntchito pa 1000BASE-T kokha.

Pulagi Seq.: Pinizani zotsatizana panthawi ya pulagi yotentha.
1) TX Fault ndiwotulutsa wokhometsa, womwe uyenera kukokedwa ndi 4.7k ~ 10kΩ resistor pa bolodi lokhala nawo ku voteji pakati pa 2.0V ndi Vcc + 0.3V.Logic 0 imasonyeza ntchito yachibadwa;logic 1 imasonyeza vuto la laser la mtundu wina.M'malo otsika, zotulukazo zimakokedwa mpaka zosakwana 0.8V.
2) TX Disable ndi cholowetsa chomwe chimagwiritsidwa ntchito kutseka ma transmitter optical output.Imakokedwa mkati mwa module ndi 4.7 ¨C 10 K resistor.Makhalidwe ake ndi awa:
Pansi (0 mpaka 0.8V): Transmitter on
