dual digital demodulators copyright ? 2015 by silicon laboratories 11.20.2015 SI21622-C60 dual dvb-t2/t/c2/c di gital tv demodulator description the si21622c integrates two sepa rate high-performance digital demodulators for the dvb-t2/t, and dvb-c2/c standards into a single compact package. leveragi ng silicon labs' proven digital demodulation architecture, the si21622c achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost, and power dissipation. connecting the si21622c to a dual terrestrial/cable tv tuner results in a high-performance and cost optimized tv front-end solution. silicon labs' internally deve loped d v b-c2 demodulator can accept a standard if (36 mhz) or low-if input (differential) and su pport all modes specif ied by the dvb-c2 standard. the main features of the dvb-c2 mode are 4096-qam, 6 or 8 mhz bandwid th, mana gement of notch insertion (broadband and narrowband), and support of multiple data slices and plps. dvb-t2 (including t2-lite) demodulator s suppor t all modes specified by the dvb-t2 standard (v1.4.1). main features of the dvb-t2 mode are, siso and miso support, fef management, fully autonomous signal acquisi tion including automatic l1 signaling parsing suppor t for all pilot patterns, and dvb-t2/t auto-detection. the dvb-t and dvb-c, including itu-t j.83 annex b, demodulators are enhanced versions of proven and broadly used si2164/67/68/ 69 silicon labs devices. the si21622c offers an on-chip blind scanning algorithm for the dvb-c, as well a s blind lock function. the si21622c embeds two independent programmable transport stream interfaces which provide a flexible range of out put modes, including a cross-bar functionality, and are fully compat ible with all mpeg decoders or conditional access modules to s upport any customer application. features - pin-to-pin compatible with all dual demodulator family: si216x2 and si218x2 - api compatible with all single and all dual demodulators - dvb-t2 and t2-lite (etsi en 302 755-v1.4.1) - bandwidth: 1.7, 5, 6, 7 or 8 mhz - nordig unified 2.5 and d-book 8 compliant - dvb-c2 (etsi en 302 769) - 16-qam to 4096-qam ofdm demodulation - dvb-t (etsi en 300 744) - nordig unified 2.5, d-book 8 compliant - dvb-c (etsi en 300 429) / itu-t j.83 annex a/b/c - 1 to 7.2 msymbol/s, c-book compliant - i 2 c serial bus interfac es (master and host) - upgradeable with firmware patch download via fast spi or i 2 c (broadcast mode supported) - dual independent differential if input for t/c tuners - gpios and multi-purpose ports (two per demodulator) - separate flexible ts interfac es with serial or parallel ? outputs and cross-bar feature - fast lock times for all standards - only two power supplies: 1.2 and 3.3 v - 8x8 mm, qfn-68 pin package, pb-free/rohs compliant applications - multi-receiver idtv: on-board or in a nim - advanced multimedia pvr stbs - pc-tv accessories - pvr, dvd, and blu-ray disc recorders demodulator_a core si21622c resetb 1.2, 3.3v sda_mast scl_mast xo xtal_i/clk_in clk_in/out demodulator_b core mp_c_a mp_a_a mp_b_b mp_d_b adc_a tc_adc_p_a tc_adc_n_a adc_b tc_adc_n_b tc_adc_p_b tv tuner i2c block_a i2c block_b tv tuner hdtv mpeg s.o.c. ts1_clk ts1_sync 8 ts1_data ts1_val ts2_sync 8 ts2_data ts2_val ts2_clk gpio0/ ts_err_b ts_a ts_b gpio1/ ts_err_a scl_host sda_host addr_a addr_b
