C-bus controlled multistandard alignment-free IF-PLL demodulators
13. Application information
Pin numbers for TDA9885HN and TDA9886HN in parentheses.
(1) For L-accent standard OP1 = LOW and OP2 = HIGH, in other cases OP1 = HIGH and OP2 = LOW.
(2) If pin OP2 outputs VIF-AGC voltage, then pin OP1 can be used for SAW switching.
(3) Not connected for TDA9885.
(4) Optional measures to improve ESD performance within a TV-set application.
(5) Application dependent.
(6) For test signal input only.
