The connector uses a BNC socket with an impedance of 75 Ohms. The
level is 800 mV PP (+/-10%).
The TS ASI interface can be operated in two modes: Burst mode, in
which the TS packets remain unchanged in themselves and dummy pack-
ets are inserted to attain the data rate of 270 Mbit/s, and single byte mode,
in which dummy bytes are inserted to provide “stuffing” to the output data
rate of 270 Mbit/s.
