. About the Transmitter:
• The STT-433 is ideal for remote control applications where low cost and longer range is required.
• The transmitter operates from a1.5-12V supply, making it ideal for battery-powered applications.
• The transmitter employs a SAW-stabilized oscillator, ensuring accurate frequency control for best range performance.
• The manufacturing-friendly SIP style package and low-cost make the STT-433 suitable for high volume applications.
Pin Description:
• GND: Transmitter ground-Connect to ground plane.
• DATA: Digital data input. This input is CMOS compatible and should be driven with CMOS level inputs.
• VCC: Operating voltage for the transmitter. VCC bypassed with should be a .01uF ceramic capacitor and filtered with a 4.7uF tantalum capacitor. Noise on the power supply will degrade transmitternoise performance.
• ANT: 50ohm antenna output. The antenna port impedance affects output power and harmonic emissions.
. Pin Description:
• ANT- Antenna input.
• GND-Receiver Ground. Connect to ground plane.
• VCC- VCC pins are electrically connected and provide operating voltage for the receiver. VCC can be applied to either or both. VCC should be bypassed with a .1μF ceramic capacitor. Noise on the power supply will degrade receiver sensitivity.
• DATA-Digital data output. This output is capable of driving one TTL or CMOS load. It is a CMOS compatible output.
