Positive CML Input Channel A with internal 50Ω pull down
Negative CML Input Channel A with internal 50Ω pull down
Positive CML Output Channel A with internal 50Ω pull up to VDD during normal
operation and 2kΩ when EN=0. Drives to output common mode voltage when
input is <V
Negative CML Output Channel A with internal 50Ω pull up to VDD during normal
operation and 2kΩ when EN=0. Drives to output common mode voltage when
input is <V
Positive CML Input Channel B with internal 50Ω pull down
Negative CML Input Channel B with internal 50Ω pull down
Positive CML Output Channel B with internal 50Ω pull up to VDD during normal
operation and 2kΩ when EN=0. Drives to output common mode voltage when
input is <V
Negative CMLOutput Channel B with internal 50Ω pull up to VDD during normal
operation and 2kΩ when EN=0. Drives to output common mode voltage when
input is <V
EN is the enable pin. A LVCMOS high provides normal operation. A LVCMOS
low selects a low power down mode.
