MC92610 SERDES User’s Manual
MOTOROLA
Loop-Back BIST Sequence System Test Mode
Step 1: Enter test mode by setting the test mode inputs as described in Table 5-4.
Step 2: Set RESET low and release high; wait PLL lock period (~32
s at 3.125
gigabaud).
Step 3: Transmit to the receiver 32 or more Idle (K28.5) characters.
Step 4: Transmit to the receiver an 8B/10B encoded PN sequence as described
above.
The transmitter will automatically go through step 3, transmitting 4,096 Idles, and step 4
upon entering this test mode. When testing is complete, the transceiver will need to be
resynchronized before normal operation can resume.
NOTE
The receiver signature analyzers assume all four channels are
being exercised. If BIST testing is being performed between
devices, or by means of external loop back on selected
channels, the unused channel receivers must be disabled or the
analyzers will not go into the PN Sync state. That is, receivers
not having an PN stimulus must have XCVR_x_DISABLE
asserted. In link multiplexer mode (LME asserted), the
secondary receiver interface (channels B and D), must be
disabled.
5.3
Loop-Back BIST Sequence System Test Mode
The test mode is the combination of the Loop-Back and BIST Sequence System Test
Modes. The device operates as described in Section 5.2.1 and Section 5.2.2. However, the
need to go through the startup sequence is eliminated because the transmitter automatically
goes through the proper sequence.
High
Low
Not Byte Sync: The receiver is in start-up or has lost byte
alignment and is searching for alignment.
High
Not Word Sync: The receiver is byte synchronized but has not
achieved or has lost word alignment and is searching for
alignment.
