that the LVPECL clock driver’s output impedance is 50
Ω. R1 is used to DC-bias the LVPECL outputs
prior to AC-coupling. Its value could be ranged from 140
Ω to 240 Ω depending on clock driver vendor’s
requirement. R2 is used together with the SerDes reference clock receiver’s 50
Ω termination resistor to
attenuate the LVPECL output’s differential peak level such that it meets the device SerDes reference
clock’s differential input amplitude requirement (between 200 mV and 800 mV differential peak). For
example, if the LVPECL output’s differential peak is 900 mV and the desired SerDes reference clock input
amplitude is selected as 600 mV, the attenuation factor is 0.67, which requires R2 = 25
Ω. Consult clock
driver chip manufacturer to verify whether this connection scheme is compatible with a particular clock
driver chip.
