对于理解VCT,需要掌握current mode和voltage mode两种模式。 对于电流输出的PHY,需要加入VCT电压;而对于电压输出的,直接bypass就行。 3. 阻抗匹配 但是缺少了阻抗匹配,我们来研究下1000Base怎样做阻抗匹配。在PCI Express的标准中,差分信号需要Zdiff=100 ohms +/- 20%,传输阻抗Z0=60 ohms +/- 15%。在Kicad中...
When it comes to the center tap on the PHY side, this should generally be connected to the signal ground using a capacitor for additional filtering purposes. Like the Bob-Smith termination resistors, each center taps for the pairs should have its capacitors to prevent any stray current flow be...
Vitesse has a white paper that discusses PHY to PHY (transformerless) which has been useful. It's pretty easy to do as the I210 is a voltage mode type versus the current mode design. Please let us know how you've progressed. Andy Siwarski Translate 0 Kudos Copy link Reply idata ...
On the line side of the PHY, data exist as analog signals: light blips on optical fiber or voltage pulses on copper cable. Signals may be distorted while in transit and recovery may require signal processing. Ethernet physical layer components include a PHY and a transceiver. PHYs The PHY ...
