PHYSICAL PACKAGING
TYPICAL PERFORMANCE GRAPHS
The receiver is packaged as a hybrid SMD module with sixteen pads spaced
0.100" on center. The castellated SMD package allows for easy prototyping or
hand assembly while maintaining full compatibility with automated pick-and-
place equipment. Modules are supplied in tube packaging.

The supply must be clean (<20mVpp), stable and free of high-frequency noise. A supply
filter is recommended unless the module is operated from its own regulated supply or
battery. Please note that operation from 4.7 to 5.2 volts requires the use of an external
200 resistor placed in series with V .

Pin 6 - POWER DOWN
Pull this line low to put the receiver in sleep mode (700 µA). Leave floating or pull high to
enable the receiver.
Pin 8 - DATA OUT

DN Pin
Internally pulled to VCC. Open collector data output with internal pullup to VCC. Recovered data
is output on this pin. Output voltage during a high bit will average VCC- 0.3V.

Pin 16 - RF IN
The receiver antenna connects to this input. It has nominal RF impedance of 50 and is
capacitively isolated from the internal circuitry.
