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.
