35 / 54 page ![]() DocID026122 Rev 5 35/54 TDA7786, TDA7786M Electrical specifications 53 3.5 Overall system performance 3.5.1 FM overall system performance Antenna level equivalence: 0 dBµV = 1 µVrms (Antenna terminal voltage with 75 Ω dummy load). Figure 19. FM input set-up Input level referred to 75 Ω antenna dummy output. Frf = 98.1 MHz, Vrf = 60 dBµV, mono modulation, fdev = 40 kHz, faudio =1 kHz audio. De-emphasis = 50 µs. Wide-band, not-tuned pre-selection application, unless otherwise specified. Table 26. FM overall system performance Parameter Test condition Min Typ Max Units Tuning range FM Eu (can be modified by the user) (automatic FE alignment available) 87.5 - 108 MHz Tuning step FM Eu (can be modified by the user) - 100 - kHz Tuning range FM US (can be modified by the user) (automatic FE alignment available) 87.5 - 107.9 MHz Tuning step FM US (can be modified by the user) - 200 - kHz Tuning range FM Jp (can be modified by the user) (automatic FE alignment available) 76 - 90 MHz Tuning step FM Jp (can be modified by the user) - 100 - kHz Tuning range FM EEu (can be modified by the user) (automatic FE alignment not available) 65 - 74 MHz Tuning step FM EEu (can be modified by the user) - 100 - kHz Sensitivity S/N = 26 dB - -6 -3 dBµV S/N @ 10 dBµV, no high-cut, DISS BW = #4 49 52 - dB Ultimate S/N @ 60 dBµV, mono 77 80 - dB @ 60 dBµV, Deviation = 75 kHz, mono 82 85 - dB @ 60 dBµV, stereo 67 70 - dB |
