T2M IP has been selling advanced ISDBT/ISDBS3 to Tier-1 Japanese TV makers since 2018. Our team has a deep understanding of the ISDBT standard and also have done a lot of field tests and customer debugs with available Demodulators in the market. Clients ISDBT Demodulator IP is developed based on this experience and also novel patented ideas in the field of algorithm designs. This is a hard core IP with no necessary microcontroller to run any algorithms and is very efficient in terms of power consumption and area. A complete evaluation Xilinx FPGA is available with a 4-weeks lead time and synthesis information in a 22nm process can be made available under NDA.
Supports different channel bandwidth: 6MHz,7MHz, 8MHz. Support both ZIF and Low-IF inputs configurations.
Digital IF Mixer to support Low-IF from 3MHz to 6MHz with 1Hz precision.
