CLOCK SIGNAL
RXRECCLK Recovered Clock from RocketIO X receiver, locked to incoming
data stream. This clock can be scaled (e.g., 64/66) relative to
incoming data rate, depending upon the specific operating mode
of the receiver.
RXUSRCLK Clock used for reading the RX elastic buffer. Clocks CHBONDI
and CHBONO into and out of the transceiver. Typically the same
as TXUSRCLK.
RXUSRCLK2 Clocks receiver data and status between the transceiver and the
FPGA fabric. Typically the same as TXUSRCLK2. Relationship
between RXUSRCLK2 and RXUSRCLK depends on width of
receiver data path.
