Whakaahuatanga
Ko te HDV's SFP24-(G)T Copper Small Form Pluggable (SFP)transceivers he mahi nui, he pai te utu o te waahanga ki te Gigabit Ethernet me nga paerewa 1000- BASE-T kua tohua i roto i te IEEE 802. 3-2002 me IEEE 802.3ab, e tautoko ana i te reiti raraunga 1000Mbps tae atu ki te 100 mita te toro atu i runga i te taura 5 miro takirua kore parepare. Ka tautokohia e te kōwae 1000 Mbps nga hononga raraunga-ruarua katoa me nga tohu 5-taumata Pulse Amplitude Modulation (PAM). Ka whakamahia nga takirua e wha o te taura me te reiti tohu i te 250Mbps mo ia takirua. Ko te kōwae e whakarato ana i nga korero ID rangatū paerewa e rite ana ki te SFP MSA, ka taea te uru atu me te wahitau o A0h ma te kawa CMOS EEPROM 2wire. Ka taea hoki te uru atu ki te IC tinana ma te pahi rangatū 2wire i te wahitau A0h.
Whakamaramatanga Pin
Hoahoa Pin
Tuhipoka:
1. Ko +/- 50 ppm te karaka
2. Ma te taunoa, ko te ROCS12-(G)T he taputapu matarua katoa i roto i te aratau matua pai
3. Kua whakahohea te kitenga whakawhiti aunoa. Kaore e hiahiatia te taura whakawhiti o waho
4. Ko te mahi 1000 BASE-T me whai atanga SGMII te punaha kaihautu me te kore karaka, me te whirihora PHY mo ia Tohu Tono AN-2036. Ki te SERDES e kore e tautoko i te SGMII, ka mahi te kōwae i 1000BASE-T anake.
