Receiver Functional Description
Loop-back data is processed the same as normally received data. Loop-back enables
at-speed self-test to be implemented for production test and for in-system self-test. The
loop-back signals are electrically isolated from the link input signals. Therefore, if the
inputs are shorted, open, or otherwise disturbed, the loop-back signals still operate
normally.
See Section 5.2 for more information on system accessible test modes.
3.3.1.1
Receiver Equalization
The media through which the signals are received, has high-frequency loss that contributes
significantly to a distortion known as Inter-Symbol Interference (ISI). In order to offset, or
equalize, the loss at high frequency, MC92610’s input amplifiers provide additional gain at
high frequencies. This is termed Receive Equalization. Receive equalization has the
greatest benefit when receiving signals through longer lengths of coax or when traversing
across a large backplane. Receive equalization is of less-benefit for short links. Receive
equalization is enabled by asserting RECV_EQ_EN high.
The input amplifier facilitates a loop-back path for production and in-system testing. When
the MC92610 is in loop-back mode (LBE set high), the input amplifier selects the
loop-back differential input signals and ignores the state on the RLINK_x0_P /
RLINK_x1_P and RLINK_x0_N / RLINK_x1_N signals. Loop back data can be routed
through either the primary or redundant input amplifier. The path taken is controlled by the
XCVR_x_RSEL signal. When XCVR_x_RSEL is low, data loops back through the primary
input amplifier, and when XCVR_x_RSEL is high, data loops back through the redundant
input amplifier.
