PHYSICAL PACKAGING
PIN DESCRIPTION
The receiver is packaged as a hybrid SIP module with five pins spaced 0.100 in.
on center.The SIP package allows easy accommodation of both horizontal and
vertical mounting requirements into a highly compact package. Its leaded design
allows for easy prototyping and simple integration into through-hole and surface-
mount designs. If the module will be bent and laid flush on the circuit board, it is
suggested that a pad of silicon or other adhesive be used to hold it in place.
Pin 1
The receiver antenna connects to this input.It is AC-coupled and has nominal RF
impedance of 50 .
Pin 2 & 4
This pin should be connected to a common groundplane.
Pin 3
This pin may be used as described in this manual to derive an indication of when
a signal is being received. In combination with simple external circuits the pin is
useful for qualifying data and implementing power-save functions . If the detect
function is not being used, a 10 K
Pin 5
Positive supply of 4 to 9 volts. The supply must be clean (<20 mV pp) stable and
free of high-frequency digital noise. A supply filter is recommended unless the
module is driven from its own regulated supply or battery.
Pin 6
This is the FM demodulator output. It has a standing DC bias of approximately 2
volts and may be used to recover analog signals such as audio or tones. Load
impedance as low as 2 K
Pin 7
This digital output from the internal data slicer is a squared version of the signal
on pin 6 (AF). This signal is used to interface with external digital decoders, or
logic devices such as a microprocessor. The output recreates the digital input to
the transmitter. Load impedance as low as 1 K
