Description
The MSB of the two bits which set the 'Will
Decode' bandwidth of the CMX661.
Selects the system frequency. High (logic ‘1’) =
12kHz; Low (logic ‘0’) = 16kHz. This signal has
an internal pullup resistor, so if left unconnected
the CMX661 will detect 12kHz by default.
The positive supply rail. Critical levels and
voltages within the CMX661 are dependent
upon this supply. This pin should be decoupled
to V
SS
by a capacitor mounted close to the
device pins.
