Figure 21. AC-Coupled Differential Connection with LVDS Clock Driver (Reference Only)
Figure 22 shows the SerDes reference clock connection reference circuits for LVPECL type clock driver.
Since LVPECL driver’s DC levels (both common mode voltages and output swing) are incompatible with
MPC8308 SerDes reference clock input’s DC requirement, AC-coupling has to be used.
This figure assumes that the LVPECL clock driver’s output impedance is 50
R1 is used to DC-bias the
LVPECL outputs prior to AC-coupling. Its value could be ranged from 140
to 240 depending on clock
driver vendor’s requirement. R2 is used together with the SerDes reference clock receiver’s 50-
termination resistor to attenuate the LVPECL output’s differential peak level such that it meets the
MPC8308’s 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
Please consult clock driver chip manufacturer to verify whether this connection
scheme is compatible with a particular clock driver chip.
