MIPI D-PHY / C-PHY Combo IP for TSMC (5nm, 6/7nm, 12/16nm, 22nm, 28nm, 40nm)
DVB-S2X WideBand Demodulator & Decoder IP (Silicon Proven)
This IP incorporates a high-speed DVB-S2 forward error corrector (FEC) which is designed to handle up to 720 Mchannel-b/s at its input. This allows for 8 simultaneous 8PSK decodes at 30 Msymbol/s. This capacity is shared between the demodulators and may be allocated at will, provided that the maximum capacity limit is not exceeded.This IP features four integrated full-band capture tuners which cover the band 950 to 2150 MHz. The signal is sampled by high-performance analog to digital converters with built in anti-aliasing filters.These ADCs connect to a high-speed digital multiplexer which allows any tuner input to feed any of the 8 demodulators.
This implements full S2 and S2X interactive services capability with short frames and full-ACM functionality including MODCOD blocking. An NCR PLL compatible with both MPEG2 and GSE streams has been implemented and may be associated with any of the demodulators to assure return-channel synchronization. A transport stream processor is able to filter on PIDs, carry out PCR re-stamping and conduct PID relabeling. In this way the wanted program streams can be, for example, output on a single multiplexed bus thus reducing wiring complexity and saving board space. The transport stream processor is also capable of handling GSE, GSE-lite, IP streams and can output raw, baseband fames.
This integrates all the features needed to provide a low-cost multi channel broadcast satellite receiver solution including: integrated crystal oscillator, SMPSs for single wire supply, DiSEqC controller, I2C repeater, FSK modem, ancillary DACs and ADCs and many unattributed general-purpose input-output ports for peripheral control. Advanced power-saving features have been implemented, the LDPC stops once the solution is sufficiently converged and the various blocks of the IC (tuner, demodulator, LDPC, Legacy FEC, and so on) may be completely shut down if not required. The device also supports Wake-on-network PID.
