High-Speed Serial Interfaces (HSSI)
— For external DC-coupled connection, as described in Section 16.2.1, “SerDes Reference
Clock Receiver Characteristics,” the maximum average current requirements sets the
requirement for average voltage (common mode voltage) to be between 100 and 400 mV.
Figure 46 shows the SerDes reference clock input requirement for DC-coupled connection
scheme.
— For external AC-coupled connection, there is no common mode voltage requirement for the
clock driver. Since the external AC-coupling capacitor blocks the DC level, the clock driver and
the SerDes reference clock receiver operate in different command mode voltages. The SerDes
reference clock receiver in this connection scheme has its common mode voltage set to
SGND_SRDSn. Each signal wire of the differential inputs is allowed to swing below and above
the command mode voltage (SGND_SRDSn). Figure 47 shows the SerDes reference clock
input requirement for AC-coupled connection scheme.
Single-ended Mode
— The reference clock can also be single-ended. The SDn_REF_CLK input amplitude
(single-ended swing) must be between 400 and 800 mV peak-peak (from Vmin to Vmax) with
SDn_REF_CLK either left unconnected or tied to ground.
—The SDn_REF_CLK input average voltage must be between 200 and 400 mV. Figure 48 shows
the SerDes reference clock input requirement for single-ended signaling mode.
— To meet the input amplitude requirement, the reference clock inputs might need to be DC or
AC-coupled externally. For the best noise performance, the reference of the clock could be DC
or AC-coupled into the unused phase (SDn_REF_CLK) through the same source impedance as
the clock input (SDn_REF_CLK) in use.
