Base-T Interface Module with Enhanced Resistor Network
EPE6133LG
circuit below guideline interconnecting PCA's EPE6133LG with transceiver chip reference controller. Further details system design, such chip pin-out, etc. obtained from specific chip manufacturer. Typical insertion loss isolation transformer/filter 0.7dB. This parameter covers entire spectrum encoded signals Base-T protocols. However, predistortion resistor network introduces some loss which taken into account determining well your design meets Standard Template requirements. quick calculation effective Thevenin's termination impedance filter follows: R(termination)= 2(68.1//274)//80695. Thus, when measuring return loss these parts bench, necessary provide shunting resistor approximatively representing four output signal sources. This calculation assumes that chip output driver source impedances negligible (less than phantom resistors shown around RJ45 connector have been known suppress unwanted radiation that unused wires pick from immediate environment. Their placement considered carefully before design finalized. recommended that there neat separation ground planes layout. generally accepted practice limit plane least 0.08 inches away from chip side pins EPE6133LG. There need ground plane beyond this point. best results, designer should design outgoing traces preferably balanced well coupled achieve minimum radiation from these traces.
