Notes
1. This general address is always valid for all tuner types of this group. It is recommended not to use this address in
applications where a further tuner becomes necessary, e.g. television sets with an option for picture-in-picture or
satellite television.
2. If the AS pin is left floating, the internal bias will automatically set the address to C2.
PROGRAMMABLE DIVIDER SETTINGS (BYTES 1 AND 2)
Divider ratio:
N = 16 × {fRF(pc) + fIF(pc)}, where (pc) is picture carrier and fRF and fIF are expressed in MHz.
fosc = N⁄16 (MHz).
N = (8192 × n13) + (4096 × n12) + (2048 × n11) + (1024 × n10) + (512 × n9) + (256 × n8) + (128 × n7) + (64 × n6) +
(32 × n5) + (16 × n4) + (8 × n3) + (4 × n2) + (2 × n1) + n0
