    GEX-P7000TV,P7000TVP 7.2 CIRCUIT DESCRIPTION - Multi-SIF GEX-P7000TVP/EW and /ES adopt the multi-Sound IF method in order to support overseas TV broadcasting methods. /EW and /ES are compatible with broadcasting methods B, G, H, D, K and I. The frequency difference between the video and sound carriers is 5.5 MHz for broadcasting methods B, G and H, 6 MHz for I or 6.5 MHz for D and K.
  • Page 59 GEX-P7000TV,P7000TVP Since detection circuits cannot be unified into one even with the above conversion, turn the IF to 6.0 MHz for all meth- ods by utilizing a frequency difference of 0.5 MHz between each IF. When IF = 5.5 or 6.5 MHz: Mix an oscillator of 0.5 MHz to turn it to 6.0 MHz.
