Function
D3TCFG.UTD is used to select the
operating mode for this pin.
DS3 Transmit Data
In Single rail mode, this unipolar serial
data output represents the DS3 signal.
TD44 is updated on the falling or rising
edge of TC44.
DS3 Transmit Positive Pulse
In dual-rail mode this pin represents the
positive pulse of the B3ZS encoded DS3
signal. TD44P is updated on the falling
edge or rising edge of TC44O.
DS3 Transmit Negative Pulse
In dual-rail mode this pin represents the
negative pulse of the B3ZS encoded DS3
signal. TD44N is updated on the falling or
rising edge of TC44O.
DS3 Receive Clock Input
The frequency of this clock is nominally
44.736 MHz.
D3RCFG.URD is used to select the
operating mode for this pin.
DS3 Receive Data
This unipolar serial data input represents
the DS3 signal. RD44 is sampled on the
falling or rising edge of RC44.
DS3 Receive Positive Pulse
In dual-rail mode this pin represents the
positive pulse of the B3ZS encoded DS3
signal. RD44P is sampled on the falling or
rising edge of RC44.
DS3 Receive Negative Pulse
In dual-rail mode this pin represents the
negative pulse of the B3ZS encoded DS3
signal. RD44 is sampled on the falling or
rising edge of RC44.
