Notes:
1) See power down control table on page 2.
- Internal pull-down resistor > 1 MΩ to VSS
2) DCF = VSS when carrier amplitude at maximum; DCF = VDD when carrier amplitude is reduced (25%
modulated)
- the output is a current source/sink with |IOUT| > 5 µA
- at power down the output is high impedance
3) Pin 14 between quartz crystal filter pins must be connected to VSS to eliminate package leadframe parasitic
capacitances disturbing the crystal filter performance. All other NC (Not Connected) pins are also
recommended to be connected to VSS to minimize noise coupling.
4) See power down control logic table on page 2.
- Internal pull-up resistor > 1MΩ to VDD
