Receive Positive Data.
Receive Data Output.
Receive Negative Data.
Bipolar Violation Detect.
Multiplexed/Non-Multiplexed Select Input.
When Low, the parallel host interface operates in non-multiplexed mode.
When High, the parallel host interface operates in multiplexed mode.
Transmit Driver Power Supply. Power supply pin for the output driver.
Transmit Tip Output.
Transmit Ring Output.
These pins are differential line driver outputs designed to drive 75
unbalanced or 120
series resistors. TRING and TTIP will be in high impedance state if the TCLK
pin is Low.
Transmit Driver Ground. Ground pin for the output driver.
Receive TIP Input.
Receive Ring Input.
These pins are the inputs to the differential line receiver. Data and clock are
recovered and output on the RPOS/RNEG and RCLK pins.
