WebThe common mode voltage of the LVPECL driver depends on supply voltage, and for 2.5V VDD it matches the LVDS common mode voltage. Termination that allows clocking an LVDS receiver with a 2.5V LVPECL driver is shown in Figure 20. In the case of 3.3V VDD, the common mode voltages of the LVPECL driver and LVDS receiver are different. WebEssentially, CD filters common mode noise that may be present in the clock signal. Equations for Figure 2: Common Mode Voltage: VCM = VDD × RN / (RN + RP) Receiver Input Single-ended Voltage Swing: VSWING= 800mVpp × RT / (50 + RT) Rewriting to find RT for the required VSWING: RT = 50×VSWING/ (800mVpp - VSWING)
