Description

The RCR-XXX-HP is ideal for remote control

applications where low cost and longer range are

required. The receiver module requires no external

RF components except for the antenna. It

generates virtually no emissions, making FCC and

ETSI approvals easy.

The super-heterodyne design exhibits exceptional

sensitivity and selectivity. A SAW filter can be

added to the antenna input to improve selectivity

for applications that require robust performance.

The manufacturing-friendly SIP style package and

low-cost make the

RCR-433-HP suitable for high volume applications.

Description

Receiver Ground. Connect to ground plane.

Digital data output. This output is capable of driving one TTL or CMOS load. It is a

CMOS compatible output.

Provides operating voltage for the receiver. VCC should be bypassed with a

.01µF ceramic capacitor and filtered with a 4.7µF tantalum capacitor. Noise on the

power supply will degrade receiver sensitivity.

Theory of Operation

Super-Heterodyne AM Detection

The RCR-XXX-HP is a super-heterodyne AM receiver with a built-in data slicer. The incoming AM

carrier is amplified and downconverted to an intermediate frequency (IF) of 10.7MHz. This IF is

filtered using a ceramic bandpass filter with a 150kHz 3dB bandwidth.

The output of the IF filter is then amplified and demodulated using diode detector. The output of

the diode detector is the demodulated AM envelope of the carrier. This signal is applied to the

data slicer to generate the TTL/CMOS output.

Data Slicer

The data slicer converts the baseband analog signal from the diode detector to a CMOS/TTL

compatible output. Because the data slicer is AC coupled to the audio output, there is a minimum

data rate. AC coupling also limits the minimum and maximum pulse width. Typically, data is

encoded on the transmit side using pulse-width modulation (PWM) or non-return-to zero (NRZ).

The most common source for NRZ data is from a UART embedded in a micro-controller.

Applications that use NRZ data encoding typically involve microcontrollers. Refer to the RCR-

XXX-HP designer’s guide for more information on using NRZ data encoding.

The most common source for PWM data is from a remote control IC such as the HC-12E from

Holtek.

Data is sent as a constant rate square-wave. The duty cycle of that square wave will generally be

either 33% (a zero) or 66% (a one). The data slicer on the RCR-XXX-HP is optimized for use with

PWM encoded data, though it will work with NRZ data if certain encoding rules are followed. The

data slicer is designed to drive one(1) TTL or CMOS load. A buffer must be used if the data

output is going to drive more than one TTL/CMOS load or if the load is a lower-impedence

(<100K).

Power Supply

The RCR-XXX-HP is designed to operate from a 5V power supply. It is crucial that this power

supply be very quiet. The power supply should be bypassed using a 0.01uF low-ESR ceramic

capacitor and a 4.7µF tantalum capacitor. These capacitors should be placed as close to the

power pins as possible. The RCR-XXX-HP is designed for continuous duty operation. From the

time power is applied, it can take up to 100mSec for the data output to become

valid.
