Description
I
Selection pins for Channel Ax emphasis (See emphasis Configuration Table) w/
100K-Ohm internal pull up
Selection pins for Channel Bx emphasis (See emphasis Configuration Table) w/
100K-Ohm internal pull up
De-emphasis enable input for Channel A0, A1, A2 and A3 with internal 100K-
Ohm pull-up resistor. Set high selects output de-emphasis and set low selects
output pre-emphasis.
De-emphasis enable input for Channel B0, B1, B2 and B3 with internal 100K-
Ohm pull-up resistor. Set high selects output de-emphasis and set low selects
output pre-emphasis.
Input with internal 100K-Ohm pull-up resistor. LB# = High or open for normal
operation. LB# = Low for loopback connection of A_RX to A_TX and B_TX.
Input switch between pin control and I
pull-up resistor. A LVCMOS high level selects input pin control, and disables I
operation. Note, during startup, input status of the control pin (LB#, RESET#,
PD#, RXD_A/B, SEL0-2_A/B, D0-2_A/B, S0-1_A/B, DE_A/B) will be latched to
the initial state of some I
Input with internal 100K-Ohm pull-up resistor, PD# =High or open is normal
operation, PD# =Low disable the IC, and set IC to power down mode, both input
and output go Hi-Z.

RESET# is an active low channel reset input for Channel A0, B0, A1, B1, A2, B2,
A3 and B3 with internal 100K-Ohm pull-up resistor. When low, the receiver
detection cycle is reset, and normal detection cycle is started after the pin goes
high.
Receiver detect output pin for Channel A0. RX50_A=High
indicates that a 50-Ohm termination was sensed at the A0TX+/- outputs.
Receiver detect output pin for Channel B0. RX50_B=High
indicates that a 50-Ohm termination was sensed at the B0TX+/- outputs.
Receiver detect enable input for Channel A0, A1, A2 and A3 with internal 100K-
Ohm pull-up resistor.
Receiver detect enable input for Channel B0, B1, B2 and B3 with internal 100K-
Ohm pull-up resistor.
