Description
The use of these multi-function depends on the setting
of MODE<1:0> or ASYNC.
ASYNC=H(MODE<1:0>=Don’t care.)
H: Cross point switching enable.
L: Cross point switching disable.
MODE2
(See Fig.5)

IN
MODE<1:0>=HH(Single-in/Single-out Mode)
H: Distribution function enable.
L: Distribution function disable.
MODE<1:0>=HL(Single-in/Dual-out Mode)
H: DDR (Double Edge input) function enable.
L: DDR (Double Edge input) function disable.
Input port switching function enable when
MODE<1:0>=HL(Single-in/Dual-out Mode).
MODE3

2: Setting the PRBS pin high enables the internal test pattern generator. It generates Pseudo-Random Bit Sequence of
2
23
-1. The generated PRBS is fed into input data latches, formatted as VGA video like data, encoded and serialized
into TXOUT output. This function is normally to be used for analyzing the signal integrity of the transmission
channel including PCB traces, connectors, and cables.
