/2.
I1+/I1- is the serial input to PBC1.
I2+/I2- is the serial input to PBC2.
I3+/I3- is the serial input to PBC3.
I4+/I4- is the serial input to PBC4.
I0+/I0- is the serial input to PBC0.
INPUT - TTL.
Port Bypass MUX SELect lines. A HIGH selects Ix. A LOW selects the
output of the previous internal device.
OUTPUT - Differential
O1+/O1- is the serial output from MUX1.
O2+/O2- is the serial output from PBC port 1.
O3+/O3- is the serial output from PBC port 2.
O4+/O4- is the serial output from PBC port 3.
O0+/O0- is the serial output from PBC port 4.
INPUT - TTL
106.25MHz REFerence CLocK for the internal Clock Multiplier PLL.
NOTE: A reference clock must be provided to the REFCLK pin in order for
the chip to power up in the right state
INPUT - TTL (NOTE: Different for VSC7127T or VSC7127R)
In the VSC7127T, MODE configures the part as a Retimer if LOW or a
Repeater if HIGH. In the VSC7127R, MODE configures the parts as a
Repeater if LOW or a Retimer if HIGH. If unused, tie HIGH or LOW.
OUTPUT - TTL:
SIGnal DETect output
INPUT - TTL: (Internal Pull-up Resistor)
Test mode input. Pull HIGH or leave open for normal operation.
