Download Specification of S840-1
Outline
S840-1 CATV modulator is a cost-effective IP/ASI to DVB C DVB T, ISDB-T, and ATSC devices, which has 512 IP inputs supporting up to 180 programs. After multiplexing and modulating process, the CATV modullador gives 4/8/12/16/20 DVB-T/DVB-C/ISDB-T/ATSC non-adjacent carriers (50MHz~960MHz) output through the RF output interface. To meet customers’ various requirements, CATV modullador is also equipped with data port for 4 MPTS output over UDP and
RTP. This is very adaptable to the newly generation DTV broadcasting system.

Technical Parameter
Maximum transmission bitrate
DVB-C
Maximum code rate = symbol rate * (188/204) * constellation BIT
6.875M 64QAM 6.875M*(188/204)*6=38.14Mbps
DVB-T
Maximum code rate=64M/7(symbol rate)* (188/204)*FEC_RATE
*Constellation BIT*(1/(1+GI))
ATSC-T
Maximum code rate=19.38Mbps
DVB-S
Maximum code rate = symbol rate * (188/204) * FEC_RATE * 2 (constellation BIT)
