Inputs

Transport Stream Input

The main input of the TT1220 is the QPSK f-connector, located on the rear
of the unit. This input interfaces directly to Low-Noise Block (LNB) and
accepts an intermediate frequency (IF) input in the 950 – 2150 MHz
(L-band) range. The unit can provide DC power, that may be used for
polarisation switching on the LNB, as well as a 22 kHz control signal. The
maximum input symbol rate is 44,5 Msym/s, while the maximum total
bit-rate is 60 Mbit/s.
An optional (factory fitted) DVB-ASI BNC connector may be present,
replacing the QPSK f-connector. This input accepts a DVB-ASI compliant
signal (188 or 204 byte), at a maximum of 60 Mbit/s.
