Description
CML inputs for Channel A0, with internal 50-Ohm pull down during normal
operation, and >200K-Ohm otherwise.
CML outputs for Channel A0, with internal 50-Ohm pull up during normal opera-
tion and 2K-Ohm pull up otherwise.
CML inputs for Channel A1, with internal 50-Ohm pull down during normal
operation, and >200K-Ohm otherwise.
CML outputs for Channel A1, with internal 50-Ohm pull up during normal opera-
tion and 2K-Ohm pull up otherwise.
CML inputs for Channel A2, with internal 50-Ohm pull down during normal
operation, and >200K-Ohm otherwise.
CML outputs for Channel A2, with internal 50-Ohm pull up during normal opera-
tion and 2K-Ohm pull up otherwise.
CML inputs for Channel A3 with internal 50-Ohm pull down during normal
operation, and >200K-Ohm otherwise.
CML outputs for Channel A3, with internal 50-Ohm pull up during normal opera-
tion and and 2K-Ohm pull up otherwise.
CML inputs for Channel B0, with internal 50-Ohm pull down during normal
operation, and >200K-Ohm otherwise.
CML outputs for Channel B0, with internal 50-Ohm pull up during normal opera-
tion and 2K-Ohm pull up otherwise.
CML inputs for Channel B1, with internal 50-Ohm pull down during normal
operation, and >200K-Ohm otherwise.
CML outputs for Channel B1, with internal 50-Ohm pull up during normal opera-
tion and 2K-Ohm pull up otherwise.
CML inputs for Channel B2, with internal 50-Ohm pull down during normal
operation, and >200K-Ohm otherwise.
CML outputs for Channel B2, with internal 50-Ohm pull up during normal opera-
tion and 2K-Ohm pull up otherwise.
CML inputs for Channel B3, with internal 50-Ohm pull down during normal
operation, and >200K-Ohm otherwise.
CML outputs for Channel B3, with internal 50-Ohm pull up during normal opera-
tion and 2K-Ohm pull up otherwise.
I2C programmable address bit A0, A1 and A4.
Loopback control input. Input with innernal 100K-Ohm oull-up resistor. LB#
= High or open for normal operation. LB# = Low for loopback connection of
A_RX to A_TX and B_TX.
Enables I2C control when LOW. Has internal 100K-Ohm pull-up resistor. A
LVCMOS high level selects input pins control, and disables I
during startup, input status of the control pin (LB#, RES_A/B#, RXD_A/B) will
be latched to set the initial register state.
Input with internal 100K-Ohm pull-up resistor, card present is an active low
signal to indicate the existence of a receiver, and will enable all channels, need to
tie low for normal operation.
