Note 1:
The following recommended discrete products are applicable for
NICEPACS, CCC and DDICE: NICE:TEA6840H,TEA6845H,TEA684
6H, NICEPACS:TEA6848H,TEA6849H; CCC:TEF6901H,TEF6903H;
DDICE:TEA6721HL. All recommended discrete products are
applicable, excluding AM LNA in: DICE2:TEF6730HWCE.
Note 2:
Phones and portable radios (IC:TEA5767/68) use varicap BB202 as the
FM oscillator.
Product highlight:
