*2: Setting the PRBS pin high enables the internal test pattern generator. It generates Pseu do-Random Bit Sequence of
223-1. 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, connec tors, and cables.
MODE2
(See Fig.5) 27 IN
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.
ASYNC=L
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.
MODE3 23 IN
Input port switching function enable when
MODE<1:0>=HL(Single-in/Dual-out Mode).
H or Open: Port switch disable.
L: Port switch enable.
ASYNC 28 IN Asynchronous function enable.
H: Asynchronous mode enable.(MODE<1:0>=Disable)
L: Asynchronous mode disable.(MODE<1:0>=Enable)
/PDWN 30 IN H: Normal operation,
L: Power down (all outputs are Hi-Z)
PRBS *2 31 IN
PRBS (Pseudo-Random Binary Sequence) generator
is active in order to evaluate eye patterns when
MODE<1:0> = LL (Dual-in/Dual-out mode) or
ASYNC=H
H: PRBS generator is enable.
L: Normal Operation
