Table 4
Crystal indication
Note
1. When a comb filter is used, the various crystals must
be connected to the IC as indicated in the pinning
diagram. This is required because the ident system
switches automatically to the comb filter when a signal
is identified which can be combed (correct
combination of colour standard and crystal frequency).
For applications without comb filter only the crystal on
pin XTALA is important (4.43 MHz); to pins XTALB to
XTALD an arbitrary 3.5 MHz crystal can be connected.
